The difference and correlation between PPR pipe and PE pipe

PPR is modified PP, PP is the code name of polypropylene, PE is the code name of polyethylene, all are polyolefins, the difference is that the molecular structure and the quantity of H are different, and PB is polybutene in polyolefin.

The molecular bond of PP is stronger than the molecular bond of PE, and the molecular weight is also large. Of course, PB is stronger. This determines the performance of the material is not the same.

The toughness of PE is stronger than that of PPR, so the low temperature resistance is higher than PPR. On the contrary, the high temperature resistance of PPR is stronger than that of PE. PE for water supply below zero environment, PPR for hot water higher than 50 degrees, water for normal temperature can replace each other. use.

PE that can be used in hot water environment, called PERT. It is a new material that has just been developed in recent years.
