3M rubber tapes have operating temperatures ranging from 176°F (80°C) to 221°F (105°C). Some, like Scotch® Linerless Rubber Splicing Tape 130C and Rubber Splicing Tape 23, have overloads temperatures up to 266°F (130°C). Because of this high heat attribute; there are many industrial settings where it is common to use rubber tape in lower voltage applications to moisture seal, pad and insulate:
