Copolymer Coated Steel Tape (also called CCST) is mainly used as a shield and moisture-proof layer inside the "jacket" of a communication cable, optical fiber (or fiber-optical) cable or similar. It consists of a steel tape, which is coated on both sides with an adherent ethylene copolymer. The Steel base is made of chrome-electroplated cold-rolled steel tape. The copolymer exhibits excellent adhesion to the steel substrate and has the chemical resistance and general characteristics of lower density polyethylene. It bonds to low, linear low, medium and high density polyethylene.
