SSBR

溶聚丁苯橡胶(S-SBR)

近年来,随着人们对环境可持续性和安全行驶的兴趣不断增加,这推动了一项技术挑战,即逐步、显著提高轮胎的性能,包括更低的能耗、更强的抓地力和更优异的耐磨性。在轮胎配方中适当的采用溶聚丁苯橡胶是成功的关键。基于Versalis技术,LVE是为数不多的批量和连续生产SSBR的制造商之一: Europrene ® K Sol R产品已成功用于“绿色”轮胎的配方中,而Sol B产品则广泛用于粘合剂、沥青和ABS改性。

溶液法丁苯橡胶是苯乙烯和丁二烯单体在烃类溶剂中由锂烷基引发阴离子聚合而成,根据苯乙烯单体的分布不同得到嵌段共聚和无规共聚两种结构的聚合物
SSBR的嵌段和无规结构赋予聚合物截然不同的性能,从而适用于不同的应用。嵌段结构的SSBR的苯乙烯含量比无规SSBR低,更适合压延和挤出工艺。它们也被用于沥青改性、生产粘合剂、高抗冲聚苯乙烯(HIPS)和ABS树脂。无规SSBR通过苯乙烯含量和丁二烯单元的微观结构为定制产品提供了多功能支持,使其在可加工性、滚动阻力、抓地力和磨耗方面具有良好的性能,并成为轮胎行业的首选。
