The 3M Scotch 23 is a premium electrical insulation tape featuring ethylene propylene rubber (EPR) backing for superior flexibility and temperature resistance. It is used for wrapping, insulating, and protecting electrical connections, splices, and components in industrial and maintenance applications. Critical verification: confirm the 0.76mm thickness meets voltage class requirements and environmental temperature range (-18°C to +82°C typical for EPR) for your specific installation.
