Factice is vulcanized unsaturated vegetable or animal oil, used as a processing aid and property modifier in rubber.
Longer chain fatty-acid containing oils such as rapeseed or meadow foam produce a harder, more desirable factice.
Cross-Linking the fatty-acid chains with sulfur (brown factice) or S2Cl2 (white factice) yields a rubbery material that improves the processing characteristics and ozone resistance of rubber. Varying the amount of factice changes the physical properties of the rubber; molded items might be 5-10% factice, extrusions 15-30%.
