PVC is widely used for pipes, window profiles, sheets, cables and injection-molded products. During processing, high temperature and shear can cause sticking, unstable melt flow and die build-up.
Paraffin wax is an important external lubricant for PVC processing. It helps reduce friction between PVC melt and processing equipment, improve extrusion stability and achieve a smoother product surface.
Khonor Wax supplies refined paraffin wax and FT wax solutions for different PVC processing requirements.
Paraffin wax forms a lubricating layer between PVC melt and metal surfaces such as screws, barrels and dies. This helps reduce sticking, friction and die build-up.
Proper external lubrication helps PVC melt flow smoothly through the equipment, supporting stable extrusion and consistent production.
The right wax grade and dosage can help PVC products achieve a smoother and more consistent surface finish.
Note: Excessive wax may cause blooming or surface migration. The optimum dosage should be determined according to the complete PVC formulation and lubricant system.
Medium-melting-point paraffin wax: Grades such as 58#, 60# and 62# for general PVC pipes, profiles and sheets.
High-melting-point paraffin wax: KH F66N-L-H and KH70H for applications requiring stable lubrication at higher processing temperatures.
Paraffin Wax + FT Wax: KH FT Wax 105 can be combined with paraffin wax to optimize the external lubrication system for demanding PVC applications.
Key factors include:
Melting point: Match the processing temperature.
Oil content: Lower oil content supports cleaner processing.
Carbon-chain distribution: Consistent distribution helps maintain stable lubrication.
Volatility: Low volatility helps reduce smoke and deposits during extrusion.
