Recently, the high-performance elastomer material sector has further intensified its efforts in the segmented field of industrial support for new materials. Focusing on the severe service conditions of industrial cables across all application scenarios, the industry has completed the refined adaptation and optimization of the full range of ordinary silicone rubber products. Leveraging two core technologies, including differentiated adjustment of cross-linking mechanisms and targeted formula modification, the upgraded silicone rubber materials effectively strengthen the safety barrier for the electrical operation of cables and establish a long-term protective foundation for extreme and complex environments such as high temperature, chemical corrosion, and strong mechanical vibration. The products fully meet the large-scale production demands of industrial cables in the whole industrial chain, covering power operation and maintenance, heavy industry and metallurgy, chemical refining, and new energy supporting projects, helping the cable manufacturing industry achieve cost reduction, quality improvement, and long-term stable production. As a core high-performance elastomer substrate in industrial supporting applications, ordinary silicone rubber covers a complete system of compliant and adaptable material matrices. It is scientifically divided into two mainstream product categories according to different cross-linking and vulcanization mechanisms, fully supporting the large-scale standardized production of various industrial cables. Among them, solid High Temperature Vulcanized (HTV) silicone rubber is suitable for continuous extrusion production lines, featuring strong molding stability, excellent comprehensive mechanical strength, and outstanding weather and aging resistance. It can be stably applied to harsh wiring scenarios such as outdoor open-air laying, heavy-load moving lines in factories, and frequent mechanical stretching. In contrast, liquid Room Temperature Vulcanized (RTV) silicone rubber systems are ideal for refined construction scenarios, including special-shaped cable sealing, precision wiring encapsulation, and insulation coating in narrow spaces. The materials can be molded in-situ at room temperature without high-temperature auxiliary heating, featuring lower construction energy consumption and wider compatibility. With dual advantages of flexible fitting and airtight protection, it effectively makes up for the performance deficiencies of traditional rubber and plastic substrates in adapting to complex working conditions. Focusing on the specialized supporting track of industrial cables, the industry has further optimized the practical application logic of ordinary silicone rubber and abandoned the extensive application mode of homogeneous general-purpose materials. In strict accordance with the core practical requirements of industrial cables, such as structural stress resistance, layered protection, and full-cycle operation and maintenance, general silicone rubber is professionally classified into two functional dedicated compounds: cable-specific insulation materials and outer sheath protective materials, realizing customized material selection tailored to different cables and actual working conditions. The insulation-modified silicone rubber strictly controls three key electrical indicators: volume resistivity, breakdown withstand strength, and low-power dielectric stability. It effectively isolates high and low voltage clutter interference, eliminates potential safety hazards such as electric leakage, breakdown, and interphase short circuits, and is applicable to core wire coating and protection of high and low voltage power cables, control signal cables, and instrument special cables, ensuring stable and safe power transmission around the clock. The reinforced silicone rubber is optimally designed with enhanced performance, including wear and tear resistance, high and low temperature alternating resistance, industrial chemical medium corrosion resistance, and outdoor ultraviolet aging resistance. It can withstand multiple external damages such as radiant heat from high-temperature metallurgical furnaces, acid-base volatile media in chemical workshops, extreme outdoor rain, snow, wind, and frost erosion, and frequent vibration and extrusion from heavy-duty equipment. The material permanently protects the internal integrity of cable structures and effectively extends the full-service life of industrial cables. The graded adaptation and optimization upgrade of ordinary silicone rubber focuses on solving the on-site operation and maintenance pain points in extreme industrial complex environments. Adopting refined targeted formula deployment technology, the new materials accurately balance two core performances: reliable electrical insulation stability and all-around physical mechanical protection. Without additional redundant formula costs, the materials comprehensively improve three practical values: material compatibility, on-site construction convenience, and low subsequent maintenance requirements. Compared with traditional ordinary rubber and plastic cable substrates, the optimized graded special silicone rubber features a wider temperature adaptation range, doubled aging-resistant service life, and greatly reduced failure rate in extreme environments. It is widely applicable to high-risk working conditions such as wiring around metallurgical steelmaking furnaces, supporting cables for chemical pipeline heat tracing, wiring for new energy wind power and photovoltaic power stations, heavy-duty power cables in heavy industrial workshops, and outdoor overhead operation and maintenance cables. It fully meets the standardized, high-end, and long-term high-quality production upgrade demands of the entire industrial cable industry. In the future, we will continue to focus on the main research and development direction of innovative new materials for industrial cables, intensifying technological research in silicone rubber substrate modification, functional compounding, and low-carbon adaptation. We will continuously iterate customized silicone rubber solutions dedicated to insulation and sheathing applications, and steadily supply high-compatibility, high-stability, and cost-effective industrial supporting elastomer new materials. We will fully support the high-quality, safe, and green long-term development of the industrial cable manufacturing industry, and consolidate the solid safety foundation for power transmission across all industrial scenarios.

Following the optimized grading iteration of ordinary silicone rubber materials, the high-performance elastomer product lineup has ushered in a new high-end upgrade. The newly launched full-specification Fumed Silicone Rubber Compound series has officially landed in the industrial cable supporting material market. Positioned as the core high-performance flagship product in the rubber compound portfolio, this series breaks through the performance bottlenecks of conventional general-purpose silicone rubber. It adopts industrial-grade advanced fumed silica nano-reinforcement core technology, combined with full-process precise molecular chain structural modular design and low-residue compounding process, fundamentally solving common pain points such as mechanical brittle fracture, thermal aging degradation, and dielectric performance attenuation of traditional elastomer materials under complex alternating working conditions, building a high-reliability, long-life exclusive protection core for high-end special industrial cables. Different from ordinary silicone rubber that relies on conventional physical blending modification, the Fumed Silicone Rubber Compound takes fumed silica as the key reinforcing functional filler. Through scientific proportioning and a homogeneous kneading process, it realizes the tight interlocking of molecular network structures inside the rubber material. The overall mechanical comprehensive performance is greatly improved, with excellent tensile resistance, tear resistance, compression resilience, and dynamic fatigue resistance. It can withstand frequent bending, reciprocating friction, and strong mechanical extrusion of dynamic equipment for a long time without deformation, cracking, or performance failure. It fully adapts to high-frequency dynamic wiring links such as mobile drag chain cables, robotic arm flexible connecting wires, and mobile power transmission harnesses in intelligent manufacturing workshops, perfectly solving the problem of the short service life of cable sheath materials in dynamic extreme mechanical application scenarios. In the core safety link of energy transmission and power engineering industries with ultra-stringent electrical safety access standards, the advantages of the Fumed Silicone Rubber Compound are fully highlighted. The optimized molecular structure effectively reduces internal dielectric loss, maintains stable volume resistivity and excellent insulation and arc resistance in the full temperature range, and will not produce insulation breakdown, partial discharge, or electrical aging failure under long-term high-voltage load and harsh environmental interference. The product fully complies with international industrial cable safety certification standards, and is specially suitable for high-voltage power transmission main cables, new energy energy storage connecting cables, marine heavy-duty power cables, and chemical explosion-proof special cable insulation and integrated sheath. It comprehensively strengthens the intrinsic electrical safety guarantee of the power transmission network. Focusing on the whole life cycle cost control and full-scenario extreme environment adaptation needs of industrial cable manufacturers, the high-performance fumed silica reinforced system endowed the rubber compound with ultra-high comprehensive environmental aging resistance. It stably exerts stable physical and electrical properties in ultra-low temperature cold resistance, high temperature heat aging, high humidity salt spray, industrial chemical medium erosion, and outdoor ultraviolet strong radiation environments. Compared with conventional silicone rubber materials on the market, its comprehensive service life is significantly extended, and the later maintenance and replacement cost of cable engineering is greatly reduced. Meanwhile, the product retains excellent vulcanization molding processability, which is compatible with existing HTV continuous extrusion and integrated cable one-time molding production lines, without additional adjustment of production process parameters, and can be quickly put into mass production and batch application. In the future, we will continue to improve the full-performance gradient silicone rubber product matrix, link ordinary general-purpose silicone rubber and high-end fumed reinforced silicone rubber compounds, and build a full-coverage customized material solution from conventional working conditions to ultra-harsh extreme working conditions. We will continue to deepen the research and development of new reinforcing filler modification and low-carbon environmental protection compounding processes, provide more high-performance, cost-effective, and process-friendly special rubber raw materials for the global industrial cable manufacturing industry, and jointly help the high-end, safe, and green upgrading of the global power transmission supporting industry chain.

Following the successful release of ordinary silicone rubber and high-performance fumed silicone rubber compound, the product matrix is further supplemented and upgraded in the functional subdivision track. The brand-new Flame Retardant Silicone Rubber series is officially launched, targeting high-standard fire prevention and safety scenarios across the whole industry chain. This series is a specially customized functional silicone rubber material independently developed for application environments with extremely strict fire protection and flame-retardant access thresholds. It perfectly complements the existing universal and high-strength rubber grades, forming a three-dimensional material protection system of conventional mechanical resistance, high-strength dynamic reinforcement, and full-standard flame-retardant safety, effectively filling the market gap of high-stability fireproof elastomer supporting materials for high-density wiring and closed electrical spaces. Different from traditional fireproof rubber materials that rely on large-dose additive blending and sacrifice physical performance in exchange for flame retardancy, the Flame Retardant Silicone Rubber series retains all the inherent excellent core properties of original silicone rubber materials in the whole formula design process. It maintains excellent high and low temperature resistance, weather aging stability, soft and elastic touch, good electrical insulation performance, and efficient processing compatibility. On this basis, advanced environmental protection flame-retardant modification technology is adopted to carry out uniform functional grafting on the molecular structure of the rubber body. Without affecting the vulcanization efficiency and mechanical strength of the material itself, it greatly inhibits the rapid propagation of open flames in case of electrical short circuit, overload heating, and external fire baking, and realizes automatic rapid self-extinguishment after leaving the fire source, effectively avoiding flame spreading along the cable harness and preventing large-area linkage fire accidents. In terms of comprehensive performance balance and safety certification adaptation, the new Flame Retardant Silicone Rubber has completed dual optimization of flame retardant grade and mechanical practical performance. It not only reaches industry-standard high-level flame retardant classification indicators, stable smoke suppression, and low heat release characteristics, but also does not reduce the tensile, tear, and bending fatigue resistance required for daily cable laying and wiring. The material is suitable for multi-dimensional cross-industry safety protection scenarios in batches. It can be widely used in internal connection lines and peripheral wiring of consumer electronic equipment with high requirements for low smoke and environmental protection, as well as key supporting cables for indoor dense power distribution, closed cabinet wiring, new energy battery harnesses, and intelligent electrical equipment. At the same time, it can also stably cope with extreme industrial working conditions such as high-temperature workshop centralized wiring, chemical plant fire-danger area layout, and public facility fire emergency backup circuits, ensuring zero fire spread risk in special environments. In actual factory production and engineering application links, the functional flame-retardant silicone rubber series retains excellent processability consistent with standard silicone rubber. It is fully compatible with existing HTV continuous extrusion equipment, integrated sheath co-extrusion production lines, and automated cable forming processes. Manufacturers do not need to replace equipment or adjust complex process parameters, which can realize seamless switching of mass production. In addition, the material features low smoke, non-toxic, and halogen-free environmental protection characteristics during combustion, which meet global environmental protection and electrical safety regulations. It reduces secondary smoke poisoning and equipment corrosion risks in case of fire, and improves the overall safety level of wiring systems from the source. With the addition of the new Flame Retardant Silicone Rubber series, our full-range silicone rubber product lineup has realized the full coverage of mechanical strength, environmental aging resistance, and fire safety core performance indicators. In the next stage, we will continue to focus on the safety upgrade needs of global power transmission and electrical connection systems, continuously develop more efficient, low-smoke, environmentally friendly and multi-functional composite silicone rubber materials, and provide one-stop, full-scenario, high-reliability customized material solutions for cable manufacturers and electrical supporting enterprises worldwide, helping the industry build a safer, greener and more stable electrical operation guarantee system.

Building on the established lineup of general-grade, high-strength reinforced, and flame-retardant silicone rubbers, we further expand the high-end functional material ecosystem with the official launch of our brand-newCeramic Silicone Rubber. Tailored for mission-critical fire-rescue power supply circuits and emergency life-support wiring systems, this innovative ceramifiable silicone rubber grade fills the high-end technical gap of traditional flame-retardant materials that fail to maintain circuit integrity under prolonged high-temperature fire exposure. It upgrades passive fire prevention to active fire-resistant circuit guarantee, completing the full-closed-loop safety protection layout of the entire silicone rubber product series for industrial cables. The core advantage of Ceramic Silicone Rubber lies in its dual-performance integration of extreme climate adaptability and high-temperature in-situ ceramification protection. In conventional daily operating environments, the material retains the inherent premium performance of premium elastomers with outstanding ultra-wide temperature stability. It can stably maintain excellent elasticity, soft flexibility, stable electrical insulation performance and intact mechanical structural strength in the extreme temperature range from -70°C low-temperature frost and cold environment to 200°C long-term continuous high-temperature working condition. It will not harden, crack, age or deform in severe cold northern outdoor environments or high-temperature heat-radiating workshops, fully meeting the long-term normal service requirements of power cables in all seasonal climates and complex factory working conditions. Once encountering sudden extreme thermal hazards, the material triggers an intelligent self-protection mechanism instantly to achieve efficient ceramification reinforcement. When the ambient temperature rises above 350°C for long-term flameless baking or suffers direct flame erosion exceeding 600°C intense fire impact, the outer layer of the rubber compound rapidly undergoes physical and chemical phase transition to form a dense, hard, high-strength integrated ceramified protective shell in situ. The ceramic shell is compact in structure, high in compression resistance and non-collapse at high temperature, which can effectively isolate external flame spreading, high-temperature heat conduction and molten metal splash impact. Most importantly, the whole-layer insulation structure remains intact without breakdown or leakage current, permanently locking the core power transmission function of the cable. The newly upgraded TC9711 Fire-resistant Ceramifiable Silicone Rubber model is professionally calibrated and positioned for the core supporting manufacturing of medium and low-voltage special fire-resistant wires and cables in the industry. It is specially recommended for core wire insulation wrapping and cable inner comprehensive protective layered structural design. In the event of building fire, chemical workshop explosion and electrical cabinet combustion accidents, it can build an unbreakable high-temperature fire insulation barrier in milliseconds, ensure that emergency fire fighting power supply, evacuation indicator circuits and linkage alarm systems keep powered on normally for a long time, avoid safety accidents such as circuit open circuit, equipment shutdown and fire spread caused by cable burning, and greatly improve the passive safety protection level of building electrical engineering and industrial fire control facilities. In terms of industrial production compatibility and engineering delivery efficiency, this ceramified silicone rubber keeps the same excellent extrusion processing performance as conventional silicone rubber materials. It is perfectly compatible with existing cable continuous vulcanization units, multi-layer co-extrusion production lines and automatic stranding and wrapping processes. Cable manufacturers do not need to add new equipment or adjust complex process formulas, realizing rapid mass production and seamless switching of finished cable delivery. While meeting national and international fire-resistant cable industry certification standards, it balances cost performance and mass production stability. At present, our silicone rubber product portfolio has fully covered ordinary mechanical type, high-strength fumed reinforced type, environmental flame retardant type and high-end ceramified fire-resistant type. In the future, we will continue to focus on the extreme safety needs of special scenarios such as fire emergency, high temperature resistance and dynamic bending, continue to develop multi-functional composite modified silicone rubber materials, and provide global cable customers with one-stop full-working-condition elastomer material solutions to escort the safe and stable operation of global power transmission systems.
