factice

Oil-resistant factice is made with castor oil.

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 meadowfoam produce a harder, more desirable factice.

Rubber erasers can have as much as 4 times as much factice as rubber in their composition.

Varying the amount of factice changes the physical properties of the rubber; molded items might be 5-10% factice, extrusions 15-30%.

(In many vintage adverts for No. 19 (and in old factice bottles), it appears that No. 19 was originally a much deeper green colour than it is now).

Navo also shot for leading online fashion magazines such as Models.com's The Ones 2 Watch and Positive Italy, Factice France, and Fiasco UK.

Soybean oil produces lower quality factice, though it can be mixed with longer-chain oils to yield factice nearly as good as that made from long chain oils alone.

Cross-linking the fatty-acid chains with sulfur (brown factice) or SCl (white factice) yields a rubbery material that improves the processing characteristics and ozone resistance of rubber.
