Description
A coarse, soft rubbery material. Factice is made by vulcanizing vegetable oil (rapeseed, linseed, or soybean) with 10-30% Sulfur for several hours at 175C to produce a dark elastomeric polymer. Alternatively, sulfur chloride can be used for room temperature vulcanization to produce a lighter color product. Factice is used for erasers and other soft rubber goods.
