Silicone Self-adhesive Tape

Our flame-retardant silicone self-adhesive tape (EPDM self-amalgamating tape) has excellent ductility and electrical insulation performance. It features outstanding resistance to ageing, ozone and ultraviolet rays with long service life and strong wrapping tension.

It is mainly used for insulation protection of substations, power plant steel structure busbars, equipment electrical joints, cable connectors and switchgear busbars.

The tape surface has no touch adhesive. No sticky residue will remain after peeling off. It will self-amalgamate into an integrated layer within a short time after wrapping. It realizes reliable sealing and waterproofing. It can be wrapped into arbitrary shapes, suitable for wrapping various electrical cable terminals and intermediate joints.

The product is anti-fouling, anti-corrosion, UV-resistant, waterproof, ozone-resistant and anti-ageing. It adapts to various environments and is perfect for outdoor operations. Service temperature: -60℃ ~ +180℃. Standard colors include red, yellow, green, black; custom colors are available upon request.

Flame-retardant silicone & EPDM self-amalgamating tape boasts outstanding ductility and insulating performance, with excellent anti-aging, anti-ozone and anti-ultraviolet features to ensure long service life and strong wrapping adhesion. Widely applied for exposed copper busbar insulation of power substations and power plants, as well as protective wrapping for equipment electrical terminals, cable connectors and cabinet busbars. Operating temperature ranges from -60℃ to +180℃; standard stock colors are red, yellow, green and black, customized colors are acceptable upon request. The tape features non-tacky surface without sticky residue after peeling off, and forms strong self-fusion rapidly after winding to realize complete sealing and waterproof. Flexible enough to wrap into arbitrary shapes, it is dirt-proof, anti-corrosion, UV-resistant, ozone-resistant and aging-resistant, perfectly suited for all environments and outdoor construction work. Its core physical indicators comply with GB/T28-2009, ASTM D2148 and UL94 standards: tensile strength ≥3.5MPa, elongation at break ≥200%, self-adhesion>3.5N/cm, UL94 V0 flame retardant grade, dielectric strength ≥22KV/mm and volume resistivity ≥1.3×10¹⁴Ω·m. Standard sizes cover width 20~100mm, thickness 0.5~1.5mm, 5 meters per roll.
