The differences between PPH pipes and PPR pipes are as follows:
Applications: PPH pipes are usually used in chemical plants, electronic semiconductor factories, pharmaceutical factories, sewage treatment plants and other fields. PPR pipes are widely used in building water supply, heating, gas and other fields, and can also be used in chemical, pharmaceutical, food and other industries. Material properties: PPH tube is mainly propylene monomer, which is a single molecular chain and does not contain ethylene monomer, so its regularity is high. However, its impact resistance is poor. To improve this defect, polyethylene and ethylene propylene rubber are added to change its toughness, resulting in PPR tubes. Performance and cost: Because PPR pipe is added with polyethylene and ethylene propylene rubber, its toughness and strength are better than PVC pipes, and ** are also higher than PPH pipes. In addition, the PPR pipe has good hot melt connection performance, high strength of the connection part, and can withstand tensile and shear stress. In general, the main differences between PPH tubing and PPR tubing are the application field, material properties, and performance and cost. PPH pipes are mainly used in chemical industry and other fields, and their material properties are high in regularity but poor in impact resistancePPR pipes are widely used in building water supply and other fields, with excellent toughness and strength, and high quality. The specific choice of pipe needs to be considered according to the actual application needs and cost.
