Silicone Self-Fusing Tape: High-Performance Industrial Sealing, Electrical Insulation for Railways & Beyond
When it comes to reliable insulation, sealing, and weatherproofing in high-demand environments, silicone self-fusing tape stands out as a trusted solution. 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. 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 Silicone Gaskets motor cables, pantograph lines, cable joints, and termination 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 protects systems from shorts, creepage, and electrical tracking in challenging climates.
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.
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. Custom colour options are available, all meeting high standards for safe use. Our Custom Silicone tapes sizes ranges from 25mm to 100mm and from 0.5mm to 0.8mm thickness.
