In general addition of filler materials will increase the modulus. The additions of calcium carbonate and talc will increase the elastic modulus, while the addition of elastic filler materials can reduce the value slightly. Filler materials increase the modulus due to their rigidity or stiffness and good adhesion with the polymeric matrix. [13]
Talc, or talcum, is a clay mineral composed of hydrated magnesium silicate, with the chemical formula Mg 3 Si 4 O 10 (OH) 2. Talc in powdered form, often combined with corn starch, is used as baby powder. This mineral is used as a thickening agent and lubricant. It is an ingredient in ceramics, paints, and roofing material.
A grain filler (pore filler or paste wood filler) is a woodworking product that is used to achieve a smooth-textured wood finish by filling pores in the wood grain. It is used particularly on open grained woods such as oak , mahogany and walnut where building up multiple layers of standard wood finish is ineffective or impractical.
The plaster is not pure plaster of Paris, but rather has additives to improve green strength, dry strength, permeability, and castability.For instance, talc or magnesium oxide are added to prevent cracking and reduce setting time; lime and cement limit expansion during baking; glass fibers increase strength; sand can be used as a filler.

Industrial resources (minerals) are geological materials that are mined for their commercial value, which are not fuel (fuel minerals or mineral fuels) and are not sources of metals (metallic minerals) but are used in the industries based on their physical and/or chemical properties. [1]
A plaintiffs' lawyer who represents 11,434 of approximately J&J's roughly 100,000 talc claimants said the company's figure is inflated, and its latest bankruptcy petition is "fraught with problems."
