Silicone Self-Fusing Tape: High-Performance Industrial Sealing, Electrical Insulation for Railways & Beyond
For dependable insulation, sealing, and protection in demanding settings, silicone self-fusing tape is the preferred choice. 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.
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. 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, Mastic Tapes it’s ideal for onboard wiring, signal systems, or installations along 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.
On the technical side, peroxide curing gives the tape enhanced strength and a longer lifespan. 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.
