Lubricants in PVC formulations prevent the material from sticking to processing equipment and enhance flow properties during manufacturing. They can be internal (improving melt flow) or external (reducing friction on processing surfaces). Proper lubricant selection is critical to maintain production efficiency and achieve desired physical properties in the final PVC products.
Used as an internal lubricant in PVC processing, stearic acid helps reduce friction between PVC molecules, aiding in easier processing and preventing sticking to metal surfaces. It improves flow characteristics and can enhance the dispersion of other additives in the PVC formulation.
EBS is a lubricant and processing aid used in PVC formulations. It improves the melt flow properties of PVC, reduces friction, and enhances dispersion of fillers and pigments. EBS also acts as a release agent, preventing PVC from adhering to processing equipment surfaces during manufacturing.
We have many other lubricants for different industries and applications for your specially needs and requirements.
