The 3M Scotch 23 Rubber Splicing Tape (19mm x 9.1m) is a premium-grade, 30-mil thick, highly conformable self-fusing ethylene propylene rubber (EPR) high-voltage tape. Designed for primary electrical insulation, cable splicing, and termination up to 69 kV, this non-vulcanising tape fuses into a homogeneous, void-free rubber mass when stretched and wrapped. It features a special easy-release polyester “snakeskin” liner that will not stick to the tape upon unwind.
