带有包括热塑性弹性体的气密层的充气制品
摘要：
本发明涉及一种包括充气气体不可透过的弹性体层(10)的充气制品(1)，所述弹性体层(10)至少包括作为主要弹性体的苯乙烯/异丁烯/苯乙烯(SIBS)热塑性弹性体。优选地，SIBS弹性体包括5％与50％之间的质量百分比的苯乙烯，数均分子量的范围为从30000g/mol到500000g/mol，Tg低于20℃。优选地，该密封的弹性体层还包括作为增塑剂的SIBS弹性体填充油，其比率优选为3pce与100pce之间。本发明的充气制品(1)优选地包括空气管或用于汽车的轮胎(1)。
摘要（英）：

The invention relates to a pneumatic article (1) including an elastomer layer (10) that is inflation gas-tight, said elastomer layer (10) including at least, as a major elastomer, a styrene isobutylene/styrene (SIBS) thermoplastic elastomer. Preferably, the SIBS elastomer includes between 5 and 50 mass % of styrene, the molecular number average ranging from 30000 and 500000 g/mol and the Tg being lower than 20 DEG C. Preferably, the sealed elastomer layer further includes as a plasticizing agent a SIBS elastomer extension oil with a ratio preferably between 3 and 100 pce. The pneumatic article (1) of the invention pefereably consists of an air tube or tyre (1) for an automobile.
