Plastic-coated copper tubes, also known as plastic-lined 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, and have a long service life. The processing technology for plastic-coated copper tubes is slightly different from that for plastic-coated copper tubes, requiring harder molds and higher temperature control during processing to produce Xinxin plastic-coated copper tubes.
