Flame Retardant Silicone Rubber Sleeving 20kV/mm Insulation -60C to 200C Cable Protection

Flame Retardant Silicone Rubber Sleeving is a flexible, halogen-free protection sleeve extruded from premium silicone rubber compound. It slides over cables, wiring harnesses and hoses to deliver electrical insulation, abrasion protection and continuous heat resistance from -60°C to 200°C. Standard bore sizes from 2 mm to 50 mm, wall thickness 0.5–3.0 mm, available in plain rolls or cut-to-length pieces.

Application Scenarios

• Automotive wiring harness: cable bundle protection near engine bays and exhaust routes, anti-chafe sleeve between body panels.
• Electrical & electronics: 20 kV/mm dielectric sleeving for power leads, transformer tails and terminal insulation.
• Industrial equipment: hydraulic hose and pneumatic line protection against abrasion, oil splash and welding spatter.
• New energy & battery packs: busbar and high-voltage cable sleeving with UL94 V-0 flame rating.
• Appliance & lighting: heater, oven and LED driver lead insulation.
• Outdoor & marine hardware: UV and ozone resistant protective covering for exposed cables and fittings.
