LOW DENSITY FOAMED ARTICLES AND METHODS FOR MAKING |
| 摘要 |
Foamed thermoplastic elastomeric polyurethane and ethylene-vinyl acetate copolymer articles are made with from about 0.1 to about 4 weight percent of supercritical fluid nitrogen based on polymer weight and from about 0.1 to about 5 weight percent of a supercritical fluid carbon dioxide based on polymer weight, with the supercritical fluid nitrogen and the supercritical fluid carbon dioxide being separately added to the molten polymer. |

1. A method for making a low density foamed article, comprising:
combining in an extruder a molten polymer selected from the group consisting of thermoplastic polyurethane elastomers and thermoplastic ethylene-vinyl acetate copolymers with (a) from about 0.1 to about 4 weight percent of supercritical fluid nitrogen based on polymer weight and (b) from about 0.1 to about 5 weight percent of a supercritical fluid carbon dioxide based on polymer weight to form a mixture, wherein the supercritical fluid nitrogen and the supercritical fluid carbon dioxide are separately added to the molten polymer; and injection molding and foaming the mixture or extruding and foaming the mixture. |
