PVC is a widely used universal plastic with good chemical stability, but it is a hard and brittle material with poor impact resistance, especially prone to brittle cracking in low temperature environments. In order to improve the impact resistance of PVC, enhance its toughness and hardness, and enable it to be better applied in various fields such as pipes, profiles, sheets, etc., it is usually necessary to add impact modifiers during the PVC processing.

Polyacrylate esters (ACR): With a core-shell structure, they can significantly improve the impact resistance and processing performance of PVC, and have good weather resistance, making them particularly suitable for outdoor products.

Significantly improving impact resistance: Impact modifiers can effectively enhance the impact strength of PVC, making it less prone to breakage under external impact, especially in low-temperature environments where the effect of impact modifiers is more pronounced.

Improving processing performance: Some impact modifiers such as ACR can not only enhance impact resistance, but also improve the processing performance of PVC, such as improving melt flowability and promoting plasticization, making the processing process smoother.
