PE wax used for PVC product processing

Polyethylene wax serves as a commonly employed external lubricant in PVC
product processing, primarily functioning to enhance processing fluidity,
prevent melt adhesion to equipment, and improve the surface finish of the
finished product.
Lubrication: During PVC processing operations (such as extrusion,
calendering, and injection moulding), polyethylene wax forms a lubricating
film at the interface between the melt and metal equipment, reducing friction
and preventing adhesion.
Promoting plasticisation: Working in conjunction with internal lubricants, it
regulates plasticisation rates to prevent over-plasticisation or insufficient
plasticisation.
Improving demoulding: Enhances the ease with which products release from
moulds, reducing defects.
Surface modification: Enhances product surface gloss while minimising surface
imperfections such as fish eyes and flow marks.
Synergistic stabilisation: Works in tandem with PVC thermal stabilisers to
enhance thermal stability.
