The role of ACR processing aids in PVC foam products is multifaceted. It can not only improve plasticizing effect, enhance melt strength, improve melt elasticity, but also increase processing efficiency and product quality，these advantages have led to the widespread application of ACR processing aids in the production of PVC foam products.

Let's take a look at its specific advantages！

Improve plasticizing effect:

ACR processing aids can promote the plasticization process of PVC, making the plasticization of PVC more uniform, thereby improving the surface glossiness and product quality of the product. By improving the rheological properties of the melt, ACR helps to enhance the dispersibility of other additives and further improve the apparent quality of the product.

Enhance melt strength and elasticity:

ACR processing aids significantly improve the cohesion and homogeneity of PVC melt, enhancing the elongation and strength of the melt. A higher melt strength is beneficial for maintaining the shape of the pores, preventing pore breakage, and thus obtaining foamed products with more uniform pore structure, lower density, and better surface quality. And it can improve the elasticity of the melt, enhance the elongation and strength of the melt, facilitate the encapsulation of bubbles, and prevent cell collapse.This improvement is crucial for the quality of foam products.

Adjust the cell density:

ACR processing aids can effectively regulate the cell density and size, form a uniform honeycomb structure, prevent gas from escaping, and reduce the density of the product. This is of great significance for reducing the density of foam sheets, improving their toughness and strength.

Improving product quality:

ACR processing aids can significantly reduce the deposition of various additives such as stabilizers and pigments on the surface of PVC products, improving the surface quality of the products. It can also improve the mechanical properties such as tensile strength, impact strength, and elongation at break of the product, thereby enhancing the overall quality of the product. Moreover, it can reduce the processing temperature of PVC and shorten the gel plasticizing time of materials, thus improving the production efficiency.
