Industrial talc has been used for more than a century as a low-cost mineral filler, anti-tack agent, mold release, processing aid, paint extender, ceramic body component, paper coating, and cosmetic ingredient across U.S. manufacturing. The largest industrial-talc consumers historically were the rubber, plastics, paint, ceramic, paper, and personal-care industries.
Per publicly filed U.S. asbestos and talc litigation, certain industrial talc supply sources — most notably the Vermont (Gouverneur), upstate New York, Texas (Allamoore), and Montana talc deposits — have contained naturally-occurring tremolite, anthophyllite, and actinolite asbestos contamination at varying concentrations through the asbestos era. Workers handling tremolite-contaminated industrial talc as a rubber compounding filler, anti-tack agent, mold release, or other processing aid were exposed to airborne amphibole asbestos fiber even where the end product was nominally specified as “asbestos-free.”
