Abstract

A resilient foamed material comprises a foamed natural or synthetic rubber and a foamed polyurethane constituent based on a cross-linked isocyanate modified polyester. The material may be formed by (a) bonding separate portions together by an adhesive, (b) dispersing one of the materials in crumb form in the other material, (c) forming one material at and curing on to the surface of the other material, or (d) forming a foamed mixture of both the materials. In an example of (c) a mixture is made of (parts by volume) 100 parts of a liquid polyester, 22 to 30 parts of toluylene di-isocyanate and 8 to 10 parts of an accelerator or activator mixture comprising an accelerator based on sodium phenate or hexahydro-dimethyl aniline, an emulsifier, and water. Dyestuffs, fillers, and plasticizers may be added. The mixture is poured on to the surface of a previously formed foam rubber body and foamed, set, and cured thereon. In an example of (d) (parts by weight) a syrup is formed from 100 parts of de-watered polyethylene adipate, and 18 parts of naphthalene 1,5-di-isocyanate. The syrup is mixed with 4 parts by weight of a mixture of toluene 2,4-di-isocyanate and toluene 2,6-di-isocyanate, and 1 part by weight of the ethyleneoxide condensation product known as "Carbowax". To the polyurethane foam-forming mixture thus formed are added 20 parts by weight of a rubber latex frothed to double volume. The mixture is stirred, allowed to rise, set, and then cured.ALSO:A resilient foamed material comprises a foamed natural or synthetic rubber and a foamed polyurethane constituent based on a cross-linked isocyanate modified polyester.
