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. Composed of advanced silicone, it immediately self-bonds when wrapped, providing a flawless, residue-free, air- and water-tight covering. 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.

Within the railway sector, this tape finds use in traction motor cabling, pantographs, cable connections, and terminal 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.

Silicone self fusing tape resists UV radiation, ozone, oil, solvents, and harsh weather making it a long-term solution for outdoor and submerged applications, including marine equipment, solar power installations, telecom towers and HVAC systems.

Peroxide-curing processes result in higher mechanical strength and greater longevity for Butyl Tapes this tape. With over 300% stretchability, it remains secure and tightly fused in high-tension scenarios.

Our range includes fire-retardant silicone self-fusing tapes, offering extra safety for technical and engineering fields. 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.
