Can you use Electrical Tape on Heat?

The function of moisture-sealing tapes such as vinyl, rubber, and mastic products is to exclude moisture from the insulation assembly and provide electrical insulation. One of these tapes — or alternately a mastic pad — generally forms the second layer of the insulation assembly. Rubber, mastic, and filler tapes are also used to pad the underlying surface by covering sharp edges.
Several grades of vinyl electrical tape are available — all of which differ in conformability, ease of unwinding, resistance of the adhesive to heat and cold, and loosening (flagging). While general-use vinyl tapes are appropriate for bundling, wire pulling, and other ancillary tasks, premium-grade vinyl tape is the best choice for permanent insulation work as it handles the broadest range of environmental factors and functions, such as cold weather.
We are pleased to stock a number of different self-fusing tapes. All are electrically insulating though some are often used for sealing work (e.g. fixing a leaking hose) in addition to electrical applications.
