Engineered to withstand intense heat, mechanical stress, and harsh environments, this high-performance insulation tape is trusted across industries — from aerospace and automotive to power generation and heavy equipment.

Silicone Coated Fiberglass Tape

What Is Silicone Coated Fiberglass Tape?

Silicone coated fiberglass tape is a heat-resistant, flexible insulating tape made by coating high-strength fiberglass fabric with specially formulated silicone rubber. The silicone layer enhances mechanical durability, water resistance, and flame retardancy, while the fiberglass core provides exceptional thermal and structural stability.

Key Features & Benefits

High Temperature Resistance: Withstands continuous exposure to temperatures up to 260°C (500°F).
Flame Retardant: Silicone coating resists flame propagation, ideal for fire-prone areas.
Abrasion Resistant: Tough outer silicone layer protects against wear, vibration, and chafing.
Moisture & Chemical Resistant: Offers outstanding resistance to water, oils, solvents, and ozone.
Electrical Insulation: Dielectric strength makes it suitable for cable harness wrapping and motor leads.

Common Applications

Wire and Cable Wrapping: Used in electric motors, generators, and aerospace wiring.
Pipe and Hose Insulation: Helps maintain system integrity in high-temperature environments.
Automotive Heat Zones: Protects harnesses near exhaust manifolds, turbochargers, and DPFs.
Welding and Foundry Safety: Serves as a protective wrap in areas exposed to molten metal splash.
Industrial Machinery: Used for insulating hot surfaces and reducing risk of operator contact.
