Applications:

WPC Calcium-Zinc Stabilizer is a high-performance functional additive specially developed for wood-plastic composite materials, featuring outstanding high plasticization performance, ultra-wide processing window and excellent capability to boost wood-plastic interface bonding strength. This stabilizer adopts a refined calcium-zinc composite formula, which is environmentally friendly, non-toxic and lead-free, fully complying with international environmental protection standards and export requirements, making it ideal for mass production of various WPC products. Its high-efficiency plasticization effect can effectively improve the melt fluidity of WPC raw materials, reduce internal friction during extrusion, injection and molding processes, lower processing energy consumption, and optimize the surface smoothness and molding efficiency of finished products. Equipped with a wide processing window, it can adapt to different production equipment, temperature ranges and raw material proportions, effectively avoiding product defects such as cracking, deformation and poor surface gloss caused by parameter fluctuations, greatly lowering the difficulty of production operation. More importantly, this calcium-zinc stabilizer can significantly enhance the interfacial bonding force between wood fiber and plastic matrix, improve the compatibility of organic and inorganic components, effectively enhance the mechanical properties, tensile strength, impact resistance and weather resistance of WPC products. It can also improve the water resistance, aging resistance and dimensional stability of wood-plastic materials, extend the service life of outdoor WPC flooring, wall panels, profiles and other products. Suitable for various PE, PP, PVC based wood-plastic composites, it is a reliable and cost-effective stabilizer solution for WPC manufacturing enterprises.
