Our company has specialized in PVC lattice boards for nearly a decade, which is the primary application area for our PVC additive products. We closely monitor key performance metrics such as density, surface hardness, board toughness, and surface flatness to ensure optimal product quality. A common challenge in this field is achieving good surface flatness in PVC lattice board products. To tackle this issue, we have developed a dedicated stabilizer and a range of P-series processing aids. These innovations improve material consistency during extrusion and significantly enhance the surface flatness of the lattice boards, providing customers with superior quality products.
