Lubricants are divided into internal and external categories.
Internal lubricant reduces friction between molecular chains and promotes material flow, increases weld line strength, reduces pressure, reduces dai and etc.
External lubricant reduces the adhesion between the polymer melt and the metal surface and also helps to reduce the process temperature. PVC is one of the polymers that cannot be processed without the presence of lubricant. For this polymer, polar lubricating molecules act as internal lubricants, while non-polar molecules act as external lubricants. For non-polar polyolefins, lubricants have the opposite effects.
Pe Wax applications
In the industry of paint, heat-melt adhesives, textiles, liquid polishes, container and tank coatings, manufacturing of polyethylene wires and cables, elastomers, rubber, masterbatch and the most common use of polyethylene waxes in the production of PVC products such as pipes, profiles, calendaring process, wall coverings, floor covering, granules and etc. is used.
