Copolymer coated steel tape
Copolymer Coated Steel Tape, consist of a steel tape coated on one side or both side with green color adherent ethylene copolymer. The copolymer exhibits excellent adhesion to the steel substrate and has the chemical resistance and general characteristics of low density polyethylene. It bonds to LDPE, LLDPE, MDPE and HDPE. The steel is electrolytic chrome, tempered to T-1 to T-3 surface condition for excellent formability and fabrication characteristics.
