一：Enhance melt strength

The foaming regulator significantly enhances the strength of PVC melt, enabling it to more fully encapsulate gas and reduce the possibility of gas escape and cell collapse. High melt strength is crucial for maintaining cell morphology, preventing cell rupture, and achieving a uniform foam structure.

二：Accelerate the plasticization process

Foaming regulator can promote the plasticization of PVC resin, making plasticization more uniform, thereby improving the surface glossiness and overall quality of the product.

三：Improve the surface quality of products

Due to the foam regulator's ability to facilitate the uniform dispersion of other additives (such as foaming agents), it can improve the surface quality of the foam board, making it smoother and more delicate.
