热塑性丁苯橡胶SBS Styrene-butadiene thermoplastic elastomer SBS

　　热塑性丁苯橡胶SBS外观为白色或浅黄多孔圆条或圆片形小颗粒，兼有橡胶和塑料的优点，具有良好的耐低温性、透气性和抗湿滑性，易于加工成型。加工工艺简单，无需硫化，能耗低，容易着色，边角料可以回收。广泛应用于制鞋、粘合剂、防水卷材、高聚物改性和道路沥青改性、电缆、玩具等行业。

　　Styrene-butadiene thermoplastic elastomer SBS has appearance of white or yellowish porous particles of rod or wafer shape. It posssesses the advantages or both rubber and plastic with excellent low temperature endurance,ventilating and wet-and-slipping, resistance. It is characterized by easy molding and coloring, simple processing, none vulcanization and low consumption or energy. The leftover bits and pieces can be recovered. It is widely used in shoes making, adhesives, waterproof materials, modification of higher polymer and road bitumen, cable and toys. The annual capacity of existing SBS plant is 150kt/a.

　　高聚物改性:可以与聚乙烯、聚丙烯、聚苯乙烯等塑料共混改性，改善其物理性能，使其获得更大范围的应用。

　　Higher polymer modification: It can blend with PE,PP and PS to modify their physical properties and widen their uses.

　　粘合剂工业:SBS可用于生产各种类型的粘合剂，特别是热熔压敏型、压敏型、溶剂型粘合剂，具有粘合力强、无毒、无环境污染等特点。

　　Adhesives: It can be used to produce all kinds of adhesive, especially hot-melt adhesive pressuresensitie, pressuresens-itive adhesive and solvent type adhesive. They have advantages of high adhesion, poisonlessness and none environmental pollution.

　　制鞋工业:SBS可用于生产各种档次的皮鞋、旅游鞋、童鞋，具有穿着舒适、抗湿滑、透气性好、易着色等优点。由于SBS不需要硫化而具有很高的强力，使得制鞋工艺流程非常简单，并具有边角料可回收的优点。

　　Shoes making: SBS can be used to make vary kinds of leather shoes, travelling shoes and children’s shoes. They have comfortableness excellent andti-slipping, ventilating, and easy coloring. Without vulcanization, SBS still has high strength, so the process of shoe-making becomes simple. Its leftover bits and pieces also can be recovered.

　　沥青改性:在沥青中加入3％—15％的SBS可改善沥青的低温屈挠性和高温抗流动性能。改善沥青的低温屈挠性可减轻沥青低温下的发硬、发脆、龟裂，提高公路、卷材的使用寿命。改善沥青的高温抗流动性能可减轻沥青在高温下的软化流淌。

　　SBS改性沥青在发达国家应用非常普遍，是有效提高公路、卷材使用寿命的最佳选择。

　　Bitumen modification: The low temperature flexing and anti-flowing property at high temperature of bitumen can be improved by adding 3% to 15%(wt%) SBS. Hardening, embrittling and cracking at low temperature of bitumen can be reduced due to improved flexing so as to extend the service life of road and rolling material. Softening and flowing of bitumen at high temperature can be improved after the anti-flowing property is enhanced.

　　As the best choice for prolonging the service life of road and rolling material effectively, SBS modified bitumen is very popular in the developed countries.
