The influence of lubricants on the thermal stability of PVC products

2020-09-16

Generally, since lubricants can lower the material temperature during processing, they have a good effect on thermal stability. More specifically, some lubricants, such as metal soaps, have a stability function by themselves; In addition, some lubricants (such as monoglycerides, etc.) can also interact with stabilizers to further enhance the effectiveness of heat stabilizers. 

There are also some internal lubricants of polyhydroxy partially esterified compounds, which can complex unstable chlorine atoms, play the role of auxiliary heat stabilizer, and also have the effect of preventing fog and eliminating static electricity.
