PVC SURFACE‑QUALITY IMPROVEMENT MODIFICATION

PVC resin demands strict molding conditions and high‑level processing requirements, with multiple constraints on formula design, which tends to trigger defects in product appearance and quality during processing. By adopting graft polymers synthesized via three‑stage emulsion polymerization as modifiers, flow‑mark defects can be effectively eliminated, and thermal elasticity during secondary processing is enhanced. This modification technology enables smooth mold filling for PVC, delivering smooth and uniform surface appearance.

Main Uses

It is critical for products with stringent appearance requirements, such as product housings, packaging boxes, display racks and medical‑equipment covers. It not only improves the aesthetic performance of end products but also raises the qualification rate of secondary molding processes.
