PVC lubricants can be divided
into PVC internal lubricant and PVC external
lubricant.
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.
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.
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.
