Silicone Self-Fusing Tape Application in Electrical Insulation for Railways & Beyond

When it comes to reliable insulation, sealing, and weatherproofing in high-demand environments, silicone self-fusing tape  stands out as a trusted solution. 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. Conforms easily around irregular shapes and is ideal for emergency leak repairs & corrosion protection on hoses, pipes, and ducts.

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. It helps prevent short circuits, surface leakage, and tracking even under harsh weather conditions.

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. The same can be provided in all custom colors without compromising the quality and is more safe to use. Our Custom Silicone tapes sizes ranges from 25mm to 100mm and from 0.5mm to 0.8mm thickness. The tape is also known as silicone self adhesive tapes / silicone tapes etc. are available for free trials on request.

At our facility, we manufacture custom-grade self-fusing silicone tapes that conform to stringent industrial and railway specifications.
