In the processing of PVC, lubricant is a very important additive, which can improve the processing performance of PVC, reduce the friction and adhesion between PVC and processing equipment, so as to improve the production efficiency and the quality of the final product.HR series of lubricating processing modifiers is a kind of lubricating processing additives with unique functions. The selection of PVC lubricants needs to be based on the specific requirements and processing conditions of the PVC products. Too much internal lubricant may lead to a decrease in the strength of PVC products, while too much external lubricant may affect the surface quality of PVC products.

1. Improving productivity
The use of PVC internal lubricants significantly reduces friction and adhesion between the PVC material and the processing equipment. By reducing the melt viscosity of the PVC, the internal lubricant allows the PVC material to pass more smoothly through the processing equipment, which reduces the energy loss due to friction and lowers the energy consumption of the production process.
2. Improving Product Quality
The use of PVC internal lubricants has a significant effect on improving the surface smoothness of PVC products and reducing production defects. By improving the flow of the PVC material, the internal lubricant helps to distribute the product more evenly in the mould, effectively avoiding surface defects, bubbles and uneven distribution caused by poor material flow.
3. Protecting processing equipment
By reducing direct contact and friction between the material and the equipment, PVC internal lubricants effectively protect processing equipment and extend its life. Additionally, the reduction in adhesion helps to make equipment cleaning and maintenance less difficult, keeping it in good operating condition, further increasing productivity and reducing operating costs.
