Copolymer Coated Steel Tape

Copolymer Coated Steel Tape

Copolymer Coated Steel Tape consists of a steel tape coated on both sides with an adherent ethylene copolymer. Steel base-tape 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. Copolymer coated steel tape is mainly used as moisture-proof layer, Shield layer of communication cable, Optic fiber cable or other cable.
