Properties
Improved surface quality: Eliminates sharkskin-like coatings and melt fracture, resulting in a smooth, high-gloss surface. Increased production efficiency: Accelerates plasticization, allowing for higher extrusion/injection speeds. Expanded processing window: Enables stable processing of PVC over a wider range of temperatures and shear rates, reducing operational difficulty. Reduced scrap rate: Minimizes defects and holes caused by poor plasticization and insufficient melt strength.

About PVC PROCESSING AID ADDITIVES

PVC processing aids, especially ACR-type additives, are "essential" rather than "additives" in rigid PVC processing. Essentially, they are "processing performance regulators," fundamentally addressing inherent processing defects in PVC such as difficulty in melt plasticization, low strength, and poor flowability through physical means. They are key technical aids for achieving efficient, high-quality, and high-value-added PVC processing. The appropriate type and dosage should be determined based on the product type (transparent/opaque, weather-resistant/non-weather-resistant), processing technology (extrusion/calendering/injection molding), and specific performance requirements (strength/elasticity/gloss).
