pvc管和ppr管区别有哪些

1, different in nature

The PPR tube, also known as the three-type polypropylene tube, adopts random copolymerization polypropylene and is extruded into a pipe and molded into a pipe. PVC is actually a vinyl polymer, and its material is a non-crystalline material.

2, production materials are different

The color of PPR and PVC tube products is different due to different production materials. The PPR tube of polypropylene material has a bright appearance and the tube is more resilient. Other color tubes can be produced according to the addition of chromophore. PVC tubes are mostly milky white and shiny on the surface, but there is no section and the material is fragile.

3, production costs are different

Due to the material and wall thickness, the production costs and prices of PPR and PVC tubes are also different. In general, the price of PPR tubes is relatively high.
