Coated Powders – Rubber Industry / Tyres

Converted Powders  –  Conveyor belting


We manufacture a range of dark factice for use in the rubber processing industry.

Factice is used as a processing aid in natural and synthetic rubbers. Factice controls the shrinkage or “nerve” of rubber mixes, thus improving dimensional stability during handling, storage and open vulcanisation. It improves filler dispersion, reduces mixing energy requirements and has the capacity to absorb large quantities of liquid plasticisers so facilitating their incorporation into soft compounds.
