Product Description

Copolymer Coated Copper Tape

Copolymer coated steel tape consists of steel tape coated on one side or both sides with an adherent ethylene copolymer. The copolymer exhibits excellent adhesion to the steel substrate and has the chemical resistance and general characteristics of lower density poly-ethylene. It bonds to low, LLDPE, MDPE and HEPE. The steel is low carbon electronic chrome-coated steel tempered to T-2 condition for excellent formability and fabrication characteristics.
