| abstract |
An expandable resin composition for puff molding shaped parts is disclosed. The composition includes a thermoplastic olefin resin such as ethylene-vinyl acetate (EVA), a solid thermally activatable blowing agent, a solid thermally activatable cross-linking agent and an inorganic metal salt such as zinc borate which provides a finished part with high temperature strength enabling removal of the shaped part from a hot mold without tearing the skin. |
