Full Description
Talc (CAS 14807-96-6) is a magnesium silicate mineral filler and extender with the molecular formula H2Mg3O12Si4, available as a powder with a density of 2.7 to 2.8 g/cm³ and melting point of 1700-1800°F. This inorganic material functions as a filling and extending agent in coatings & construction, oil & gas, and plastics & polymers industries. Talc exhibits low solubility (less than 1 mg/mL at 70°F) and requires appropriate handling precautions due to its GHS Danger classification with health hazard pictogram.
