热塑性橡胶SIS

SIS是苯乙烯—异戊二烯—苯乙烯嵌段共聚物，是一种新型的热塑性弹性橡胶体。因其具有热塑性、高弹性、熔融指数和溶液粘度低，与增粘树脂相容性好的特点，广泛用于粘合剂、涂料、塑料及沥青该性等领域，可制备包装袋、妇女卫生巾、纸尿裤、双面胶及标签等方面。中石化巴陵石化公司合成橡胶事业部于1996年实现SIS工业化生产，由此填补了国内空白，成为至目前为止中国大陆**可以大规模生产SIS的石化企业。经过多年的研究与开发，现SIS年产量已达3万吨，产品牌号多样，质量稳定，可充分满足国内外客户的需求。

Thermoplastic slastomer SIS

Sis, a styrene-isoprene-styrene block copolymer, is a new thermoplastic elastomer rebber, owing to its thermoplastic property, high elasticity, low melting index and viscosity and good compatibility with tackifying resin, SIS can be used in the fields of adhesives, coatings and plastic and asphalt modification, and can be used to produce packing bags, sanitary napkin, diaper, double-side adhesive tape and labels. The Synthetic Rubber Division of Baling Petrochemical Co. succeeded in the large-scale Industrial production of SIS in 1996, filling a domestic gap in the field and becoming the only petrochemical enterprise in the mainland of China that can produce SIS in large scale by now. After dozens of research and development, the production capacity is 30 kt/a now and the products have various specifications and stable quality fully satisfying the demand of the international customers.
