Plastic-coated copper tubes, also known as coated copper tubes or PVC-coated copper tubes (abbreviated as PVC-coated copper tubes), are made from copper tubes as raw materials. They undergo deep processing to ensure a sturdy bond between the plastic and the copper tube, featuring resistance to aging, corrosion, and cracking, with a long service life. The processing technology for plastic-coated copper tubes differs slightly from that of coated copper tubes; initially, a harder mold must be selected, and the temperature control during processing needs to be higher to produce the Rainjoy plastic-coated copper tubes.
