Little Known Facts About Mastic Tapes.

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. Its adaptability lets it handle odd shapes, so it’s great for rapid leak repair and shielding against corrosion on various equipment.



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.

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.

Resistant to Silicone Medical Tubes UV, ozone, oil, and solvents, it is built for lasting performance outdoors and underwater—ideal for marine gear, solar sites, telecom infrastructure, or HVAC.

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 colours without compromising the quality and is more safe to 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.
