HellermannTyton Helatape Power 810 Self-Amalgamating Rubber Tape, 19mm x 9.1m, Black HTAPE-POWER810-EPR-BK

HellermannTyton Helatape Power 810 is a self-amalgamating EPR tape that fuses into a single, homogeneous mass without any adhesive, creating a permanent, void-free moisture seal. Unlike PVC tapes that rely on sticky backings, this tape bonds only to itself, making it ideal for insulating and protecting cable joints, terminations, and repairs up to 69 kV.

Highlights

• Self-amalgamating ethylene propylene rubber (EPR) – no adhesive, no residue
• Excellent electrical insulation with dielectric strength of 30 kV/mm
• Permanent moisture seal: water-resistant and weatherproof
• Wide operating temperature range from -40 °C to +90 °C
• High elongation at break (>900%) for conformable wrapping
• UV resistant for outdoor use
• RoHS compliant

In daily use

This tape is used by electrical professionals for insulating low and medium voltage cable joints, sealing cable ends against moisture, and repairing damaged cable sheaths. It is applied by stretching and wrapping; the tape amalgamates within minutes to form a solid rubber layer. For best results, apply at temperatures between 0 °C and +30 °C.
