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. Made from advanced silicone rubber, it bonds to itself instantly when stretched and wrapped, forming a seamless, air-tight and water-tight layer — without leaving any 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. 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. 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.
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.
Technically, this Mastic Tapes tape is peroxide-cured for better mechanical strength and durability. With over 300% stretchability, it remains secure and tightly fused in high-tension scenarios.
