Stockwell Elastomerics believes that customers should be able to select a product just the way they like it in this case, silicone rubber with or without talc. Silicone rubber is often manufactured with a light application of talcum powder to prevent the rubber from sticking to itself.

compressive strength. The addition of piropilit in the burnt lightweight brick will decrease the value of the strength. Porosity and modulus of elasticity values indicate that the addition of a filler piropilit as much as 5-15% by weight of cement on the burnt brick would increase the value of "OPTIMIZATION AND USE OF TALC IN DIRECT COMPRESSION ,Tablets with very low friability, high crushing strength, rapid dissolution rates, good weight uniformity, content uniformity and potency of drugs were obtained. At similar compression forces, tablet hardness with the 300 grade of Alabama, Altac, and Beaverwhite talcs were significantly greater than corresponding 400 and 500 grades.
