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. Composed of advanced silicone, it immediately self-bonds when wrapped, providing a flawless, residue-free, air- and water-tight covering. Its adaptability lets it handle odd shapes, so it’s great for rapid leak repair and shielding against corrosion on various equipment.



It has exceptional thermal stability, operates effectively in temperatures ranging from -40°C to +250°C, making it ideal for high-heat environments such as engine compartments, turbines, or heating elements. The tape also offers high dielectric strength, often exceeding 20 kV/mm, making it perfect for electrical insulation, splicing, and cable bundling.

In the railway industry, silicone self-fusing tape is extensively used in traction motor cables, pantograph lines, cable joints, and termination kits. 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.

Silicone self fusing tape resists UV radiation, ozone, oil, solvents, and harsh weather making it a long-term solution for outdoor and submerged applications, including marine equipment, solar power installations, telecom towers and HVAC systems.

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. We manufacture silicone tapes in sizes from 25mm to 100mm wide and Silicone Conductor Cover 0.5mm to 0.8mm thick.

The tape known as silicone self fusing tape, silicone self adhesive tapes, silicone tapes etc are available for free trials on request.
