Wholesale PVC White Powder Polyvinyl Chloride PVC Resin Sg5 Sg3

PVC material has good weather resistance and can resist the influence of natural factors such as UV, oxidation, and moisture, maintaining its performance and appearance stability. PVC materials can improve their flame retardant performance and meet safety requirements by adding flame retardants. PVC material has good wear resistance and can maintain its smooth and beautiful surface during long-term use.

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.
