PVC-M pipes are more user-friendly and are committed to improving the toughness of PVC and reducing the design insurance factor. In order to ensure the durability of toughness, the method of only increasing toughness without plasticizing was adopted, and finally the PVC-M pipe was developed.
On the premise of basically not reducing the long-term strength, the toughness reaches an impact that is 5~10 times higher than that of UPVC, and the notched impact strength is ≥30Mpa (20℃), which is more than three times that of UPVC. After the toughness is increased, the damage sensitivity is reduced, and the pipe is less likely to be injured or the degree of injury is greatly reduced, which has less impact on long-term strength. Therefore, the design safety factor can be adopted as 1.6. In this way, PVC-M pipes not only have the advantages of PE pipes, but also have the advantages of easy installation and maintenance of UPVC. Therefore, it has broader prospects than UPVC and PE pipes.
