Cotran KC80 Rubber Mastic Tape

KC80 is a self-bonding rubber tape used for electrical insulation up to 2kV and for moisture sealing 
on all types of telecommunications and solid dielectric power cable. It consists of an ethylene 
propylene rubber (EPR) backer overlaid with a tacky, temperature stable, electrical grade mastic. 
The EPR backer’s strong “memory” to return to its original shape when stretched during taping provides 
significant centripetal force that allows the mastic to flow into and fill every crevice and indentation in 
a cable jacket thereby giving a superior moisture seal in a splice or termination. Both the backer 
and mastic components of KC80 have excellent electrical characteristics. The tape is suitable for use 
with conductors rated at 90°C with an emergency overload rating of 130°C. The tape is also resistant 
to corrosion, chemicals and ultra violet light. Its 1.65mm thickness facilitates rapid protection build-up. 
Use in conjunction with KC63 premium vinyl electrical tape for optimal performance.
