Description

[0002] PE is polyethylene. Generally, the application range of PE pipe water supply pipeline is below 40℃, and it cannot be used for hot water delivery pipeline. PE pipe is a highly crystalline, non-polar thermoplastic resin. After the PE pipe is produced by the extruder, it will be cooled by the spray cooling equipment to make it harden and form quickly.
