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.

However, the impact strength of PVC resin is relatively low, and to improve this performance, impact modifiers are usually added. The elastic particles of impact modifiers can reduce the total stress caused by silver lines, and utilize the deformation and shear bands of the particles themselves to prevent the expansion and growth of silver lines, absorb the impact energy introduced into the material body, and thus achieve the goal of impact resistance.
