Many PVC foam board manufacturers are addressing common surface defects, as these defects greatly reduce product grade and lead to high scrap rates. The core reason is that the melt plasticization is unstable and the cell structure of foam is fragile during extrusion and foaming.

So this is where high-performance Acrylic processing aids play a decisive role. ACR has a unique polymer acrylic structure that blends perfectly with PVC resin, effectively accelerating uniform plasticization and balancing melt viscosity. It eliminates incomplete fusion and unstable melt flow, which are the main causes of surface defects.

More importantly, our HTX ACR processing aids significantly improve the melt strength of PVC. It locks the internal foam gas, prevents the bubble from breaking and collapsing, and forms a fine, uniform and dense cell structure. This stable foaming process can provide a super smooth, high gloss board surface with consistent texture and no stripes.

In addition to excellent surface treatment, it can also stabilize extrusion pressure and torque, adapt to high-speed production, and reduce finished product warping and defects. Compatible with all common stabilizer systems, it is applicable to all kinds of rigid PVC foam board formulations without additional adjustment of the formulation.

Our professional Acrylic processing aids are optimized for the production of PVC foam board. To improve the surface quality of your product!
