Polyvinyl chloride resin is an important organic synthetic material with excellent physical and chemical properties, and is widely used in various fields. PVC materials have good corrosion resistance to most chemicals, making them suitable for various environments and usage scenarios.

In addition to conventional PVC resin, there is also a type of chlorinated CPVC resin, which is a new type of engineering plastic. The molecular bond irregularity and polarity of CPVC resin increase, resulting in improved solubility, chemical stability, and heat resistance. The thermal deformation temperature, Vicat softening temperature, and maximum operating temperature of CPVC resin are higher than those of conventional PVC resin, so it has a wider application prospect.
