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.
