Lubricating PVC processing aids are a type of additive specifically designed to improve the processing performance of polyvinyl chloride (PVC) materials. They reduce the viscosity and friction of PVC resin, allowing for smoother flow during processing such as extrusion, injection molding, etc. These types of additives typically include high molecular weight polymers, waxes, and fatty acids. Lubricating additives not only improve processing efficiency, but also enhance the physical properties and appearance of the final product.
Extrusion molding: Lubricating PVC processing aids can effectively reduce melt viscosity, minimize mechanical wear, and improve production rate and product smoothness during the extrusion process.
Injection molding: During the injection molding process, these additives can improve the filling and flowability of the mold, ensure smooth product surfaces, and reduce defects.
Film and sheet production: Lubricating additives improve the transparency and flexibility of PVC films and sheets, enhancing their tear resistance and wear resistance.
Pipes and profiles: In the production of pipes and profiles, lubricating additives can improve the flowability during the molding process, reduce the occurrence of bubbles and defects during the production process.
Environmental protection and performance optimization: Modern lubricant additives often use environmentally friendly materials, which not only effectively improve processing performance, but also meet the market's demand for green products.
