Flame Retardant Silicone Rubber Launched

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.
