PVC film has been widely used worldwide due to its low cost, good processing performance, and strong chemical corrosion resistance. However, with the continuous improvement of market requirements for PVC film performance, PVC processing aids, as a key factor in enhancing PVC film performance, are gradually becoming the focus of the industry.

1. PVC processing aids can effectively disperse polymer chains in PVC resin, reduce intermolecular aggregation, and thus improve the transparency of the film. By optimizing the formula and dosage of additives, bubbles and impurities in the film can be significantly reduced, allowing light to pass through the film more evenly.

2. PVC processing aids lubricate PVC molecular chains, reduce intermolecular friction, and thus improve the flexibility of the film. This lubricating effect makes the film less prone to breakage during processing and use, especially in low-temperature environments, and can maintain good flexibility.

3. PVC processing aids can effectively disperse stress in the film, reduce stress concentration points, and thus improve the overall flexibility of the film. This stress dispersion effect not only improves the impact resistance of the film, but also extends its service life.
