Patent number: 4677133Abstract: Elastomer compositions suitable for use in foaming operations and elastomeric cellular products and processes of forming such products. The elastomer compositions comprise a mixture of two thermoplastic rubber compounds, at least one of which has a vinyl aromatic component and a higher aromaticity than the other rubber compound. The compositions also contains a nucleating agent which functions when gas is entrained in the molten elastomer formulation to enhance the neutrophilic structure of the elastomer. An unstable resin is also present in the elastomer compositions. This resin is oxidized or thermally decomposed as the foamed product is cured to produce a relatively nontactified skin. Cellular elastomeric products may be formed by incorporating an inert gas into the molten elastomer compositions by the use of gas infusing equipment or by the decomposition of blowing agents. The blowing agents may be supplied to the molten elastomer composition entrained within a plasticizing oil.Type: GrantFiled: January 17, 1986Date of Patent: June 30, 1987Assignee: Q'SO, Inc.Inventor: Larry F.
