During the large-scale production of PVC foam boards, profiles, sheets, and footwear materials, companies often encounter common processing challenges: uneven cell sizes, board collapse or shrinkage, and rough, dull surfaces. Furthermore, high-temperature, high-speed production lines are prone to issues such as incomplete plasticization, low pass rates, and performance degradation in high-filler formulations. These problems not only hinder efficiency but also significantly increase raw material waste and rework costs, acting as a critical bottleneck for the high-quality mass production of PVC products.

Compared to traditional processing aids, HTX processing aids offer exceptional resin compatibility. They form stable molecular bonds with PVC resin particles and efficiently transfer heat and shear forces during processing. This effectively lowers processing temperatures and accelerates resin plasticization, addressing the root causes of uneven plasticization and molding instability.

In the production of PVC foam products, this additive significantly enhances melt strength, stabilizes the foam structure, and refines cell morphology. It effectively eliminates defects such as inconsistent cell sizes, cell coalescence, board collapse, and rough, uneven surfaces, resulting in vastly improved product flatness and surface smoothness.

To meet industry demands for high-filler formulations, HTX processing aids effectively counteract the drop in melt strength caused by high calcium carbonate loading. They enhance filler-carrying capacity without compromising mechanical properties, enabling companies to optimize formulations and reduce raw material costs.

Additionally, the product’s excellent heat resistance and non-migratory nature make it ideal for industrial high-temperature, high-speed production lines. It does not migrate during processing or affect the product's appearance, color, or mechanical properties—such as tensile strength and wear resistance—thereby significantly reducing defect rates and increasing the yield of high-quality finished products.

Currently, HTX processing aids are widely used in sectors such as PVC foam boards, wall panels, SPC flooring, pipes and profiles, and foam footwear materials, meeting the mass production requirements for a range of mid-to-high-end PVC products. Thanks to its stable performance, excellent compatibility, and exceptional cost-effectiveness, it helps numerous manufacturers achieve their goals of improving quality, increasing efficiency, and reducing costs, making it a preferred core additive in the PVC processing industry.
