Silicone Self-Fusing Tape: High-Performance Industrial Sealing, 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. Crafted from high-grade silicone rubber, this tape fuses to itself the moment it's stretched and applied, creating a continuous, air- and water-tight seal with zero adhesive residue. Its adaptability lets it handle odd shapes, so it’s great for rapid leak repair and shielding against corrosion on various equipment.



With remarkable heat resistance, it performs flawlessly from -40°C up to +250°C, making it suitable for engine bays, turbines, or hot zones like heating elements. 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. 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, Silicone Gaskets solar power installations, telecom towers and HVAC systems.

Peroxide-curing processes result in higher mechanical strength and greater longevity for this tape. With over 300% stretchability, it remains secure and tightly fused in high-tension scenarios.

Our range includes fire-retardant silicone self-fusing tapes, offering extra safety for technical and engineering fields. The same can be provided in all custom colours without compromising the quality and is more safe to use. Tape sizes can be customised from 25mm to 100mm width and 0.5mm to 0.8mm thickness.

Samples of our silicone self-fusing tape (also called silicone self-adhesive or silicone tapes) are available on request.
