HTX high molecular weight PVC processing aid is a premium acrylic-based additive tailored for rigid PVC products. With a molecular weight of 1–8 million, it exhibits excellent compatibility with PVC resin, addressing poor melt strength and uneven fusion issues in rigid PVC processing. This specialized aid optimizes rheological behavior, laying a solid foundation for high-quality rigid PVC manufacturing.

Melt strength is critical for rigid PVC extrusion and molding. HTX high molecular weight processing aid significantly boosts PVC melt strength via long-chain molecular entanglement, maintaining shape stability under high shear. It minimizes extrusion swelling and die drool, enabling precise dimension control for pipes, profiles, and sheets. This stability supports continuous high-speed production.

Surface quality defines the aesthetics and durability of rigid PVC goods. HTX processing aid improves surface smoothness and gloss by eliminating flow marks and reducing surface roughness. It enhances the uniformity of rigid PVC products, whether for construction profiles, pressure pipes, or decorative sheets. The high-gloss surface also reduces post-processing costs.

HTX high molecular weight PVC processing aid stands out as a reliable solution for rigid PVC manufacturers. It balances processability, mechanical properties, and surface quality without compromising PVC rigidity. Ideal for extrusion, injection molding, and calendering, it helps manufacturers upgrade product quality and increase production efficiency. Choose HTX for superior rigid PVC processing performance.
