Title (EN) DAMPING THERMOPLASTIC ELASTOMER BLENDS EXHIBITING CLARITY
(FR) MÉLANGES ÉLASTOMÈRES THERMOPLASTIQUES AMORTISSEURS PRÉSENTANT DE LA CLARTÉ
Abstract:
(EN) A thermoplastic elastomer compound includes polyester-type thermoplastic polyurethane and no greater than about 30 weight percent of styrene-isobutylene-styrene block copolymer. The compound has good clarity, as exhibited by a haze of no greater than about 60%, or 50%, or 30%, according to ASTM D 1003. Additionally, the compound has good damping properties, as exhibited by a resilience or vertical rebound of less than about 25% according to ASTM D2632.
(FR) L'invention concerne une composition élastomère thermoplastique comprenant un polyuréthane thermoplastique de type polyester et pas plus d'environ 30 pour cent en poids de copolymère séquencé de styrène-isobutylène-styrène. La composition a une bonne clarté, telle que manifestée par un trouble inférieur ou égal à environ 60 %, ou 50 %, ou 30 %, selon la norme ASTM D 1003. De plus, la composition a de bonnes propriétés d'amortissement, telles que manifestées par une élasticité ou un rebond vertical inférieurs à environ 25 % selon la norme ASTM D2632.
