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. The tape also offers high dielectric strength, often exceeding 20 kV/mm, making it perfect for electrical insulation, splicing, and cable bundling.

Railways rely on silicone self-fusing tape for applications in traction cables, pantograph lines, joints, and cable termination. Mastic Tapes 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 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. We offer these tapes in custom colours, so you don’t sacrifice safety or quality. Our Custom Silicone tapes sizes ranges from 25mm to 100mm and from 0.5mm to 0.8mm thickness.
