PVC Lubricants are divided into two areas, internal and external lubricants.
Internal lubricants effect
1.A reduction in friction heat
2.reducing melt viscosity
3.Postpone gelation
4.Improved flow charateristics
External lubricants effect
1.Delayed gelation
2.Improved gloss
3.Reduced friction
4.Provide release properties
Internal lubricant used on PVC mainly including:
Stearic acid, G60
External lubricants used on PVC mainly including:
PE wax
