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. The tape’s flexibility allows it to wrap neatly around complex forms, making it perfect for quick leak fixes and safeguarding hoses, pipes, or ducts from corrosion.
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.
In the railway industry, silicone self-fusing tape is extensively used in traction motor cables, pantograph lines, cable joints, and termination kits. Because it blocks moisture, stands up to high voltage, and absorbs vibration, it’s ideal for onboard wiring, signal systems, or installations along Mastic Tapes the tracks. 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.
FR (Fire Retardant) grade silicone self-fusing tapes are available, making them well-suited for engineering or safety-critical use. 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.
