Is rigid PVC double wall corrugated plastic pipe with HDEP pipe one kind?
The materials used are different, the process and formula, and the processing temperature are different. The PVC formula has hundreds of thousands. Hope to adopt, thank you
It is a hard PVC amorphous thermoplastic resin with certain additives of vinyl chloride monomer after the polymerization and made (such as stabilizers, lubricants, fillers, etc.). But strictly speaking, UPVC is hard PVC, and PVC UPVC is not hard, rigorous and scientific discussion should be UPVC UPVC, which does not contain or use plasticizer, hard PVC containing plasticizers (general formula PVC powder + plasticizer + auxiliary plasticizer stabilizer + + + + class processing aid filler toner)
The HDEP drain is mainly made of HDPE resin (the formula is simple and the price will be cheaper after synthesis)
