Non-Oxidized Polyethylene Waxes in PVC Compounds
Non-oxidized polyethylene waxes are non-polar additives and primarily function as external lubricants. They reduce friction between the PVC melt and hot metal surfaces of processing equipment, decrease the risk of scorching, and help ensure stable passage of the material through the extruder and shaping tools.

Non-oxidized waxes can be produced by different methods: direct synthesis from ethylene, synthesis from syngas via the Fischer–Tropsch process, and polyethylene depolymerisation. The most cost-effective method is typically polyethylene depolymerisation; however, such waxes may have a broader molecular weight distribution and less stable batch-to-batch characteristics.
Direct synthesis from ethylene enables the production of waxes with a narrower molecular weight distribution and good reproducibility of properties. Fischer–Tropsch waxes form a separate group. They offer high efficiency and, in many formulations, allow the required lubricating effect to be achieved at lower dosage levels.
Main functions of non-oxidized polyethylene waxes:
- act as external lubricants;
- reduce friction between the PVC melt and metal surfaces of processing equipment;
- help prevent scorching and material build-up;
- modulate plasticisation rate, enabling better control of melt behaviour in different zones of the extruder;
- contribute to improved gloss and a stable surface appearance of finished products.
Non-oxidized polyethylene waxes are also used in the production of asphalt–concrete mixtures to extend the service temperature range, helping to ensure that both severe frost and high temperatures do not adversely affect the quality of road surfaces.
