Lubricating processing aids are widely used in various plastic processing techniques, including extrusion molding, injection molding, calendering, and blow molding. In the production of PVC products such as pipes, profiles, films, and sheets, lubricating agents not only improve the processing performance of the materials, but also enhance the mechanical properties and surface smoothness of the products.

During the extrusion molding process, lubricating processing aids can reduce the friction between the polymer melt and the equipment surface. This not only reduces energy consumption, but also reduces equipment wear and improves production efficiency. Meanwhile, lubricating agents help prevent melt fracture and improve the surface smoothness and uniformity of the product.

During the injection molding process, lubricating additives can promote the fluidity of polymers in the mold, ensure the uniformity of product filling, reduce mold wear, and facilitate the smooth demolding process. This can improve the dimensional accuracy of the product and reduce surface defects.

In rolling and blow molding processes, lubricating additives improve the rheological properties of polymers to ensure uniform thickness and surface quality of films or sheets. The use of lubricating agents can also reduce the accumulation of frictional heat during processing and avoid degradation caused by material overheating. And it can improve the processability of the polymer, reduce the thickness fluctuation of the film, enhance transparency and surface smoothness. It can also prevent adhesion problems of the film during the production process and improve the operational stability of the production line.

In the production of PVC products such as pipes, profiles, and sheets, lubricating processing aids not only improve the flowability and processability of the melt, but also enhance the surface smoothness and impact resistance of the products. This is important for PVC products that require high-quality surfaces and mechanical properties.
