3M Scotch® No. 23 Rubber Splicing Tape is a high-performance, self-amalgamating tape widely used for electrical insulation and environmental sealing. Made from ethylene propylene rubber (EPR), it offers excellent resistance to moisture, UV exposure, ozone, and weathering.

This tape fuses to itself without the need for adhesive, creating a solid, void-free insulation layer that ensures long-lasting protection. Its flexibility allows it to conform easily around irregular shapes, cables, and connectors, making it ideal for aircraft wiring, grounding, and maintenance applications.

Commonly used in aviation, MRO, and industrial electrical systems, Scotch No. 23 delivers reliable insulation performance even in harsh operating conditions.
