Scotch® Fire and Electric Arc Proofing Tape 77 is a premium non-adhesive tape designed to protect most types of electrical cables when exposed to failures in an adjacent cable. Its specially formulated material expands in fire to form a thick char buildup between the flame and the cable. The resulting firewall acts as a heat shield and flame barrier, thus protecting the wrapped cables and accessories.
Scotch® Tape 77 is elastomeric and unsupported, which makes it very conformable. The exceptional conformability provides better product control while wrapping and yields more uniform coverage. The tape's thin cross section also reduces the overall weight compared to other methods while providing arc protection.
