PVC lubricants can be divided
into PVC internal lubricant and PVC external
lubricant.
Â
The main function of 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.
Â
 The 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.
Â
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.
