3M™ Tape 23 is a professional-grade Rubber Splicing Tape engineered for high-performance electrical insulation. Made from highly conformable, self-amalgamating Ethylene Propylene Rubber (EPR), Scotch Tape 23 is designed for moisture-sealing and insulating joints and terminations up to 69 kV. 3M Tape 23 stretches easily up to 100% for void-free builds, providing reliable protection in both low and high voltage applications.
Part Numbers: 7000090116, 7000034802, 7000007286, 7000034850, 7000138529, 7000138512.
Scotch 23 is ideal for insulating, padding and sealing electrical connections where consistent dielectric strength and flexibility are essential. With excellent elongation, 3M Rubber Splicing Tape conforms to complex cable profiles and irregular shapes while resisting moisture ingress. The non-vulcanising, shelf-stable construction and unique polyester liner make Tape 23 easy to handle and apply – ensuring clean, efficient use with every roll. This product is perfect for cable joints, motor leads, bus bars and terminations in harsh environments.
