Abstract: A friction material for use as a brake lining in automobiles, trucks, buses or similar vehicles. The brake lining contains no more than traces of asbestos and utilizes the mineral vermiculite as a basic constituent. The formulation of the brake lining comprises a non-fibrous natural or synthetic mineral or mineral-like material together with a small quantity of non-asbestos fibers and acicular mineral particles which on being compressed at ambient temperatures and at pressures of 1700 to 2600 p.s.i. has significant green strength in the order of 2 to 25 p.s.i. and also has appropriate thermal resistance, frictional properties, and shear and flexural strengths, together with a thermosetting resin as the basic components together with other organic and inorganic materials as friction modifiers and fillers. The mineral preferably comprises vermiculite, and together with the resin comprises preferably about 35% to 95% by weight of the brake lining formulation.

Abstract: Flexible intumescent sheet materials containing low density filler components to provide low density mounting mats which reduce the mount density to prevent ceramic diesel particulate monolith cracking are disclosed.

Abstract: An improved dental composition which is opaque to X-rays comprising a polymerizable matrix and inorganic filler. The inorganic filler are formed of particles of zeolitic alumino-silicate of at least one metal selected from the group consisting of calcium, strontium, barium, lanthanum, rare earth metal having an atomic number of 58-71, tantalum and hafnium. The invention also provides dental prosthetic appliances found from said dental compositions.

Abstract: A stabilizer for use in a halogen-containing resin is described comprising a crystalline aluminosilicate substituted with ions of a metallic element belonging to Group II or Group IVA of the Periodic Table for Group I (M) metal ion contained in said aluminosilicate and containing 10% by weight of less, as M.sub.2 O, of residual Group I metal ions.

Abstract: A heat curable material in the form of a moldable and extrudable paste comprises a mixture of inorganic fibers, an elastomer, silicone resin and various optional fillers, all mixed with a suitable solvent. The material cures into a durable solid having excellent physical properties and superior thermal insulating characteristics.

Abstract: This invention is directed to a process for stabilizing polyvinyl chloride molding mixtures which comprises admixing(a) from about 0.2 to 5 parts by weight of a sodium aluminosilicate of small particle size;(b) from about 0.05 to 1.5 parts by weight of one or more calcium salts of fatty acids;(c) from about 0.05 to 0.5 parts by weight of one or more zinc salts of fatty acids;(d) from about 0.2 to 2.0 parts by weight of partial esters of polyols and fatty acids; and(e) from about 0.1 to 10 parts by weight of thioglycolic acid esters of polyols and/or thioglycolic acid esters of monofunctional alcohols per 100 parts by weight of polyvinyl chloride or copolymer of vinyl chloride.
