4571-Z Flame-Retardant Fumed Silicone Compound

Product Overview
The 4571-Z is a specialized milky-white fumed silicone elastomer engineered for applications where fire safety and structural integrity are paramount. By integrating advanced flame-retardant technology with a fumed silica base, this grade provides a robust defensive barrier against combustion while maintaining the high elasticity and easy processing characteristics required for industrial manufacturing.

Product Description
The TC-9710 is a cutting-edge ceramic-forming silicone compound designed to provide ultimate circuit integrity and structural protection during fire emergencies. In the event of a fire, this material undergoes a unique transformation, shifting from a flexible rubber state into a hard, protective ceramic layer. This "ceramification" process ensures that critical systems continue to function even under extreme thermal stress, making it an indispensable material for modern safety engineering.

Liyang Tiansheng Insulating Materials Co., Ltd. supplies ceramifiable thermoplastic polyolefin (TPO) cable compound in the form of uniform white cylindrical granules, engineered as a high-performance insulation and sheathing material for low- and medium-voltage fire-resistant cables. The product is ready for direct extrusion processing and is compatible with standard cable manufacturing lines.

The defining characteristic of this compound is its ceramification behavior: upon exposure to flame or extreme heat, the material undergoes a ceramic-forming reaction, producing a dense, rigid inorganic ceramic layer that preserves the cable's insulation integrity and maintains circuit continuity under fire conditions. This performance advantage makes it a superior alternative to conventional XLPE and PVC insulation materials in fire-critical applications.

In terms of processability, the TPO base matrix delivers excellent melt flow consistency, dimensional stability, and smooth extrusion surface quality — supporting high-speed, continuous production with low scrap rates. The compound is fully halogen-free and low-smoke, releasing minimal toxic gases during combustion, meeting the stringent safety standards required for buildings, rail transit, and industrial environments.

Typical downstream applications include fire survival power circuits, emergency lighting cables, rail and metro wiring systems, and industrial control cables. Liyang Tiansheng offers customized compound development to meet specific performance targets and client formulation requirements, providing cable manufacturers worldwide with a consistent, high-quality insulation material supply.

Product Overview
The 5280 is a high-quality, translucent, general-purpose precipitated silicone rubber designed for industrial applications that require a perfect balance of durability and cost-efficiency. Engineered for excellent processing performance, it provides high mechanical strength and superior electrical insulation when paired with the T-1A vulcanizing agent.

Liyang Tiansheng Insulating Materials Co., Ltd. is a professional manufacturer of silicone rubber high-voltage cables engineered for new energy vehicles (NEVs), including battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). Our HV cables are designed for critical power transmission links between battery packs, motor controllers, on-board chargers (OBC), and DC/DC converters.

Constructed with premium-grade silicone rubber insulation and jacketing, our cables deliver exceptional performance across an operating temperature range of -60°C to +200°C — significantly outperforming conventional PVC and XLPE alternatives. This makes them ideally suited for the demanding thermal environments found in EV powertrain compartments and underbody applications.

Each cable features a tinned copper braid shield layer for effective electromagnetic interference (EMI) suppression, ensuring stable operation of onboard electrical systems. The silicone construction provides outstanding flexibility and bend fatigue resistance, enabling easy routing in complex wiring harness configurations with minimal bend radius requirements. The material also offers excellent resistance to oils, coolants, and chemical exposure, supporting full vehicle lifecycle reliability.

All products comply with the UL94 V-0 flame retardancy standard and are fully halogen-free, meeting the environmental and safety requirements of global automotive markets.
With years of expertise in insulating materials, Liyang Tiansheng offers full customization of conductor cross-sections, cable lengths, and shielding configurations to meet the specific requirements of OEMs and Tier 1 automotive suppliers worldwide.
