Sculpey
Description
[Polyform Products, Schiller Park, IL] A brand name for a plasticized Polyvinyl chloride modeling compound. Sculpey feels like modeling clay but it does not shrink on baking and is available in a wide variety of colors. Sculpey contains about 15% di-(2-ethylhexyl) terephthalate (DOTP) plasticizer. Prior to 1991, it contained di-(2-ethylhexyl) phthalate (DEHP) which is now listed as a carcinogen. The soft, uncured Sculpey should not be placed on painted or varnished surfaces as the plasticizer will dissolve these materials. Additionally, uncured Sculpey may be affected by solvent based paints. Sculpey instructions recommend baking at temperatures below 130C (275F). After baking, the material solidifies and can be sanded, drilled, carved, or painted.
