What is plastic lubricants?
PVC Lubricant is an indispensable additives in PVC processing.
Adding proper amount of lubricant in PVC
can improve the fluidity of PVC
melt, improve production efficiency, prevent the decomposition of PVC
caused by friction heat, and improve quality of the products’ surface.
According to function, it can be divided into external lubricant and internal lubricant.
External lubricants because the poor compatibility with PVC resin,
and it is easy to migrate from the inside
of the resin melt to the
surface to form a lubricant interface layer, thus reducing the friction
PVC melt and the plastic mechanical
Internal lubricant contains polar groups and has good compatibility
with PVC. It can reduce the
intermolecular force of PVC, reduce the
intermolecular friction, reduce the viscosity of PVC melt and
the melt fluidity
