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. 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. High dielectric performance (20 kV/mm and up) ensures it can insulate, splice, or bundle cables safely.

In the railway industry, silicone self-fusing tape is extensively used in traction motor cables, pantograph lines, cable joints, and termination kits. Moisture-proof, voltage-resistant, and vibration-absorbing, it is the solution for train electrics, signals, and outdoor rail gear. It protects systems from shorts, creepage, and electrical tracking in challenging climates.

Its durability against UV, ozone, chemicals, and weather makes it reliable for marine, solar, telecom, or HVAC needs, even when submerged.

Peroxide-curing processes result in higher mechanical strength and greater longevity for this tape. Outstanding elongation (over 300%) guarantees it wraps tightly and fuses well, even when pulled.

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 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.
