Why is PPR pipe cold brittle?

PPR is the abbreviation of Polypropylene Random, and its chemical name is random copolymerized polypropylene, which is commonly known as type III polypropylene. It is produced by random copolymerization of propylene monomer and a small amount of ethylene monomer (3%-5%) under the action of heating,......

Several experiments on testing the quality of PPR water pipes

High-quality water pipes with the same specifications have thicker pipe walls, more materials, and better thermal insulation and pressure resistance.

PPR pipe has unique advantages
