TPE COMPOSITION HAVING GOOD RESEAL, ARTICLES PRODUCED THEREFROM, AND METHOD |
摘要 |
<p>A thermoplastic elastomer (TPE) composition is provided which contains a blend of a hydrogenated styrenic block copolymer (SBC) having a number average molecular weight (Mn) greater than about 200,000 Daltons (Da), a polypropylene, a mineral oil, and at least one filler. The composition has a hardness less than about 80 Shore A and is resealable. An article produced from such a TPE composition reseals itself so as to exhibit no leakage after puncture. A method for preventing leakage in an elastomeric article involves providing an elastomeric article formed from the TPE composition, puncturing the elastomeric article by inserting a sharp object, and removing the sharp object; the article reseals itself such that no leakage occurs from the punctured article after removal of the sharp object.</p> |
