Fire retardant Tape
Scotch 77 Tape is an arc and fireproofing tape designed to protect all types of electrical cables. Its unique formulation allows the manufacture of an unsupported elastomer that expands in fire to provide a thick char build-up between the flame and cable. This insulating firewall acts as a heat shield and flame barrier, thus protecting the cables and accessories. All adjacent wrapped cables and accessories are protected when exposed to fault arcs until limiting devices can interrupt the faulted circuit. Because 77 Tape is unsupported, it is extremely conformable. Installers can wrap cables and irregularly shaped accessories easier and more rapidly. This exceptional conformability enables better product control while wrapping, and more uniform coverage. Also, the tape’s thin cross sections greatly reduce overall weight compared to other methods while providing equal or better fire and arc protection times. Cable heat is also dissipated more rapidly than with other forms of thick fire protection, and, therefore, does not de-rate the cable. One-half lap wrap provides adequate protection for most installations. However, additional wraps can be applied if conditions warrant without requiring a reduction in conductor loads. Now cables and accessories can be fire and arc proofed more economically, far easier and more rapidly than ever before.
Tape Features: Flexible unsupported elastomer – clean, easy to apply, eliminates cuts and contusions of hands. Conformability provides wrinkle-free wrapping and complete coverage with minimum effort. Provides fault arc protection to adjacent wrapped cables and accessories. Intumescent characteristics – expands in fire to provide an insulating firewall between the flame and cable. Self-extinguishing, will not propagate flame. Will last and maintain its fire and arc proofing properties for the life of the cable. Resistant to water, salt water, acids, sewage and ultraviolet light. Can be removed and reused. Standard roll sizes for fast convenient installation.
