SIS是苯乙烯—異戊二烯—苯乙烯嵌段共聚物，是一種新型的熱塑性彈性橡膠體。因其具有熱塑性、高彈性、熔融指數和溶液粘度低，與增粘樹脂相容性好的特點，廣泛用于粘合劑、涂料、塑料及瀝青改性等領域，可制備包裝袋、婦女衛(wèi)生巾、紙尿褲、雙面膠及標簽等方面。經過多年的研究與開發(fā)，現SIS年產量已達3萬噸，產品牌號多樣，質量穩(wěn)定，可充分滿足國內外客戶的需求。
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.
