Sis, a styrene-isoprene-styrene block copolymer, is a new thermoplastic elastomer rubber, 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 3 kt/a now and the products have various specifications and stable quality fully satisfying the demand of the international customers.
