Abstract: Inelastic films comprising at least one elastomeric core and a surrounding inelastic matrix preferably prepared by coextrusion. The film when stretched and allowed to recover will create an elastomeric composite.

Abstract: Zinc-compatible silica particulates, useful for the formulation of a wide variety of improved dentifrice compositions, have an effective compatibilizing amount of zinc values chemically bonded to surface area sites of the particles.

Abstract: Provided is a moldable sheet comprising a synthetic organic fiber nonwoven fabric for reinforcing resinous molded article and a resin composition having impregnated the nonwoven fabric. The nonwoven fabric comprises opened single filaments having a specific fineness and bundles of filaments laid parallel with one another having a specific total fineness distribution, said single filaments and said bundles of filaments being bonded with a binder of non-fiber form. By employing this construction, the nonwoven fabric can, when used for reinforcing resinous article, improve the impact resistance, i.e. falling ball impact resistance and Izod impact resistance, which have been poor with conventional glass-fiber reinforced resinous shaped articles, while maintaining the high mechanical strength of the resinous article.
