(1) Lubrication

Internal lubrication: reduce the viscosity of the melt, improve the processing fluidity, reduce energy consumption (e.g. injection moulding, extrusion).

External lubrication: prevent the melt from adhering to the mould, reduce precipitation and scaling, and improve mould release.

(2) Surface modification

Improvement of gloss: make the surface of products smoother and brighter (e.g. PVC film, sheet).

Anti-scratch: added to engineering plastics (e.g. ABS, PC) to reduce surface scratches.

(3) Dispersing additives

Help pigments and fillers to disperse evenly (e.g. colour masterbatch, functional masterbatch).

(4) Anti-adhesion

Prevent film and sheet from sticking between layers (e.g. PE cling film, BOPP film).

(5) Abrasion resistance

Improve the abrasion resistance of engineering plastics (e.g. nylon, POM).
