The FR Color Insulation Tape is made available by us that include high-temperature compression seals and thermal insulation wraps to contain heat and protect hoses, cables, workers, and surrounding components from heat. Fiberglass tape can also be coated with a high-temperature silicone elastomer. Electricians generally use only black tape for insulation purposes. The other colors are used to indicate the voltage level and phase of the wire (colored tape sometimes is called 'phasing tape'). This is done on large wire which is available only in black insulation. The FR Color Insulation Tape is made for use in various places.
