Improving WPC Product Quality with Advanced Foaming Agent Technology

Common Issues in WPC Sheet and Profile Production

In the production of WPC (Wood Plastic Composite) sheets and profiles, many manufacturers encounter technical problems such as black lines in the surface layer, no foam cells in the core, and poor plasticization.These issues not only affect the visual appearance of the final product but also weaken its mechanical properties and reduce its market competitiveness.

A common cause of these problems lies in the improper selection or unstable performance of the foaming agent. For example, when using low-quality WPC sheet AC foaming agent or NC foaming agent for WPC profiles, the gas release rate and decomposition temperature may not match the plasticization process, leading to uneven cell structure and surface defects.
