Abstract: A novel, improved battery separator material particularly adaptable for use in maintenance free batteries. The battery separator material includes a diatomaceous earth filler, an acrylate copolymer binder and a combination of fibers comprising polyolefin, polyester and glass fibers.

Abstract: Novel, improved binders comprising a combination of heat reactive polymers. The novel binders are especially useful as saturants for fibrous sheet materials to provide high quality shoeboard materials.

Abstract: Novel, improved insole composites comprising a non-woven fiber batt needle-punched to one side of a woven polymeric scrim and which is subsequently impregnated or saturated with a curable or cross-linkable polymer.The invention also presents novel processes for producing the insole composites and for manufacturing footwear comprising the novel, improved insole composites.

Abstract: A battery separator material which is folded to form an envelope is heat sealed along at least two opposing edges thereof to form a battery separator. The separator material is comprised of discrete polyolefin pulp fibers in a sufficient amount to heat seal the separator along its edges. The fibers are bound by an organic polymeric binder. A process of forming the battery separator is also disclosed.

Abstract: Synthetic sheet material is resistant to decay by fungus and other microbial organisms and particularly useful in shoe construction, mulch papers and the like. The material comprises a uniform distribution of cellulose and optionally synthetic fiber within a matrix or binder and is formed from a furnish of the fibers; a metallic quinolinolate which lends the material decay resistant; a polymer colloid such as an acrylic latex which prevents the coagulation of the subsequently added elastomeric binder by the metallic quinolinolate; and a cationic polymer which acts as a retaining agent for the metallic quinolinolate in the synthetic sheet material.

Abstract: A high temperature resistant compressible sheet material has a thickness of 0.001 to 1 inch and includes a crosslinked elastomer as a binder and high temperature staple fibers. A major amount of a particulate filler which has been chemically modified to coreact with the crosslinked elastomer is incorporated into the sheet material. The binder preferably has incorporated therein an addition polymerized silane coupling agent. The sheet material is fabricated according to papermaking techniques. The sheet material is useful in the fabrication of gasketing and in heat shields.
