The lubricating effect of micronized wax is primarily ‘internal lubrication’. During the processing of polymeric materials such as plastics and rubber (e.g., extrusion, calendering, injection moulding), the wax powder disperses uniformly within the melt, migrating between polymer molecular chains to reduce intermolecular friction, thereby lowering melt viscosity.
Key advantages:
Reduced viscosity and enhanced flowability: Facilitates easier processing and conserves energy.
Improved production efficiency: Enables higher extrusion or injection moulding speeds.
Enhanced surface gloss of finished products: Wax migration forms a smooth surface layer.
Reduced equipment wear: Provides lubricating protection for internal walls and screws.
Common Application Areas:
PVC Processing: An indispensable lubricant in rigid PVC pipes and profiles (door/window extrusions).
Engineering Plastics: Improves flow and demoulding properties during processing of PC, ABS, nylon, etc.
Masterbatches and Functional Compounds: Serves as a carrier lubricant, aiding dispersion of pigments or functional additives.
