Rubber Mineral

EXTENDER. A low-graxily material used in paint, ink. plastic, and rubber formulations chiefly to reduce cost per unit volume by increasing bulk, Extenders include dialomaccou.s earth, wood flock, mineral rubber, liquid asphalt, etc. Microscopic droplets of water fixed permanently in a plastic matrix are an efficient extender tor polyester resins. In the food industry, the term refers to certain extruded proteins, especially those derived from soybeans, which are used in meat products to provide equivalent nutrient values at lower cost. Made from defatted soy flour, they are often called textured proteins. 

Grisonite or Mineral Rubber. See under Asphalt A496-R... 

Ext. D C. Colorants not certifiable for use in oral products but considered safe for use in externally applied products specifically excludes colorants that may have oral toxicity, extender. A low-gravity material used in paint, ink, plastic, and rubber products to reduce cost per volume by increasing bulk. Some example of extenders are diatomaceous earth, wood floe, mineral rubber, etc. In the food industry, soybean is used as an extender in meat products, providing equivalent nutritional value at a lower cost, extract. A product derived from vegetable matter by the application of solvents, heat or pressure to separate it from the other constituent parts, extraction. The process of treating a natural raw material with an organic solvent. The solvent portion containing the extracted material is filtered and the solvent removed. The extract will contain nonvolatile as well as volatile components. Oleoresins, resinoids, concretes, and absolutes are all produced by extraction. 

Elaterite i- la-t3r- rit [Gr Elaterit, fr. Gk elater] (1826) n. Infusible asphaltic pyrobitumen of petroleum origin, sometime described as mineral rubber or mineral Caoutchouc. 

Paraffin waxes, their mixtures with petrolatum, and low molecular mass polyethylenes are often used as processing aids Struktol 40MS (Schill Seilacher) and mineral rubber also improve processing behavior and can enhance adhesion between halobutyl and unsaturated rubbers.
