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.

Polyvinyl chloride resin, also known as PVC resin, is a thermoplastic polymer formed by polymerization of vinyl chloride monomers. PVC resin is a white or slightly yellow amorphous powder with excellent chemical stability, electrical insulation, wear resistance, chemical corrosion resistance, penetration resistance, and comprehensive mechanical properties.
