High Quality KC70 Tape Manufacturer Rubber Adhesive fireproof insulation tape
Description :
- KC70 is a self-amalgamating nitrile-butadiene rubber tape used for protecting all types of power and telecommunication cables from arcing and fire damage.
- The tape is put up on an easily removed disposable separator and conforms well during the taping process.
- When exposed to flame KC70 will generate a thermally insulating residue for cable protection.
- The tape is ideal for use wherever cables are located in close proximity such as manholes, vaults, service entrance in large buildings, cable trays, substations, subway lines, train stations, industrial plants and other situations where arc or flame protection is desired.
- KC70’s self-amalgamation property allows quicker and more secure application compared to competing products that are not self-amalgamating.
Application:
- Arc and fire proofing of all types of cables that are close together in confined spaces.

What is Self-amalgamating tape?
»»»From Wikipedia, the free encyclopedia
Self-amalgamating tape is a non-tacky silicone-rubber tape which when stretched and wrapped around cables, electrical joints, hoses and pipes combines or unites itself into a strong, seamless, rubbery, waterproof, and electrically insulating layer. Unlike many other polymers and fibers, it is heat-, sunlight-, and weather-resistant. This type of tape is also described, particularly in the United States, as "self-fusing" or "self-vulcanizing". In the US Air Force (and elsewhere) it is called centerline tape due to a colored line running down the center used to assist with even wrapping. It is also called F4, rescue, and fix-it tape.
While not adhesive as such, its self-amalgamating property makes it function as like adhesive tape when wrapped over itself. It is supplied in rolls with an interleaving layer, to prevent the tape from amalgamating before use. It may optionally be made with an iron-oxide additive which adds high thermal conductivity. This tape is used extensively in aviation and aerospace wiring applications as a splice or wrapping tape due to its non-flammability.[citation needed] It can be used for emergency repair of leaking low-pressure hoses and pipes.
Compared to most other electrical and utility tapes, centerline tape is not particularly tough mechanically. Silicone rubber feels soft but is also susceptible to cuts and abrasion, having low "tear resistance". This weakness is made worse because this tape is wrapped while stretched, and remains under internal tension even while fused, so that any nicks or cuts may start to tear and expand without additional external tension.[6] However these same properties, combined with the lack of traditional gum adhesive,makes tape removal if needed, quick, clean, and easy.
