Silicone Self-Fusing Tape: High-Performance Industrial Sealing, Electrical Insulation for Railways & Beyond

In industries where insulation, sealing, and weatherproofing are critical, silicone self-fusing tape proves its value time and again. Made from advanced silicone rubber, it bonds to itself instantly when stretched and wrapped, forming a seamless, air-tight and water-tight layer — without leaving any residue. It conforms easily around irregular shapes and is ideal for emergency leak repairs & corrosion protection on hoses, pipes, and ducts.



Engineered for extreme temperature endurance, it works from -40°C to +250°C — ideal for engines, turbines, or other high-heat sites. Its impressive dielectric strength, typically above 20 kV/mm, makes it the go-to for electrical insulation, cable splicing, or wire bundling.

Railways rely on silicone self-fusing tape for applications in traction cables, pantograph lines, joints, and cable termination. Its ability to resist moisture ingress, high voltage, and mechanical vibrations makes it perfect for onboard electrical systems, signal boxes, and trackside installations. The tape safeguards against shorting, leakage, and tracking even during extreme weather.

Resistant to UV, ozone, oil, and solvents, it is built for lasting performance outdoors and underwater—ideal for marine gear, solar sites, telecom infrastructure, or HVAC.

Technically, this tape is peroxide-cured for better mechanical strength and durability. It maintains excellent elongation (over 300%), ensuring secure wrapping and tight fusion even under tension.

We have silicone self fusing tapes of FR(Fire retardant) grade which makes and keep it ideal in engineering applications. Custom colour options are available, all meeting high standards for safe use. Our Custom Silicone tapes sizes ranges from 25mm to 100mm and from 0.5mm to 0.8mm thickness.

You can request free Silicone Conductor Cover samples of silicone self-fusing, self-adhesive, or silicone tapes to try.
