PVC lubricant can be divided into PVC internal lubricant and PVC external lubricant. The main function of PVC external lubricants is that they have poor compatibility with polymers and are easy to migrate from the melt to the outside, so they can form a lubricating thin layer at the interface between plastic melt and metal.PVC internal lubricant has good compatibility with the polymer, which can reduce the cohesion between the polymer molecules in the polymer, so as to improve the internal friction heat generation and melt fluidity of the plastic melt. Most lubricants have the double effects of internal and external lubricants, rather than a single role, such as stearic acid. When the initial processing temperature is low or the amount is large, the external lubrication characteristics are dominant. When the temperature is high, the compatibility with PVC is increased and the amount is appropriate, the internal lubrication is the main role..
External Lubricants
PVC external lubricants serve the purpose of creating a lubricating thin layer at the interface between the plastic melt and metal. These lubricants have limited compatibility with polymers, making them prone to migration from the melt to the exterior. As a result, they effectively reduce friction and enhance the overall processing of PVC.
Internal Lubricants
PVC internal lubricants are characterized by their strong
compatibility with polymers. They work by reducing the cohesion
between polymer molecules within the polymer matrix. This reduction
in internal friction heat generation enhances the melt fluidity of
the plastic melt, further improving the processing of PVC.
