Biorenewable copolyester thermoplastic elastomers |
| 摘要 |
A thermoplastic elastomer compound is disclosed having copolyester elastomer, epoxidized soybean oil, and vulcanized vegetable oil. The compound has a biorenewable content of at least about 50 weight percent of the compound. The compound can be used to make a plastic article needing a Shore A hardness of from about 40 to about 70. The compound is a sustainable solution for extruded or molded articles. |
