FT wax used in plastics: injection moulding, extrusion and pelletisation

Fischer-Tropsch wax is widely used in plastics processing, particularly in
industries such as injection moulding, extrusion and pelletising.
1. Main Functions
Internal lubricant: Reduces intra-molecular friction in the plastic melt,
improves flowability, and reduces torque and energy consumption.
External lubricant: Reduces friction between the melt and the surfaces of
metal equipment (barrels, screws, moulds), prevents adhesion, and improves
demoulding performance.
Dispersant: Helps pigments and fillers (such as calcium carbonate and talc)
disperse evenly within the resin, preventing agglomeration.
2. Specific Applications
Injection Moulding: Improves melt flow index, reduces injection pressure,
minimises mould fouling, enhances demoulding efficiency, and produces
smoother product surfaces.
Extrusion: Reduces extruder current, minimises material build-up at the die,
and improves output and dimensional stability.
Pelletising: In masterbatches, aids pigment wetting and dispersion, and
reduces filtration pressure drop.
