用于轮胎的多层层合物
摘要：
用于轮胎的气密弹性体层合物，其中所述层合物包含至少两个重叠的层的弹性体：第一层，其由基于至少一种包含聚苯乙烯和聚异丁烯嵌段的热塑性弹性体构成，包含聚苯乙烯和聚异丁烯嵌段的热塑性弹性体的量包含在大于50至100phr(重量份/每100重量份弹性体)的范围内；第二层，其由基于至少一种二烯弹性体和至少一种苯乙烯热塑性弹性体(TPS)的组合物构成，二烯弹性体的量包含在大于50至95phr的范围内，苯乙烯热塑性弹性体的量包含在5至小于50phr的范围内。
摘要（英）：

An airtight elastomeric laminate for tyres is provided, wherein said laminate comprises at least two superposed layers of elastomer: a first layer, consisting of a composition based on at least one thermoplastic elastomer comprising polystyrene and polyisobutylene blocks, the amount of thermoplastic elastomer comprising polystyrene and polyisobutylene blocks being included within a range of more than 50 to 100 phr (parts by weight by 100 parts by weight of elastomer); a second layer, consisting of a composition based on at least one diene elastomer, the amount of diene elastomer being included within a range of more than 50 to 95 phr, and on at least one styrene thermoplastic elastomer (TPS), the amount of styrene thermoplastic elastomer being included within a range of from 5 to less than 50 phr.
