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-butadienethermoplastic elastomer sbs has appearance of white or yellowishporous particles of rod or wafer shape. it posssesses theadvantages or both rubber and plastic with excellent lowtemperature endurance,ventilating and wet-and-slipping, resistance.it is characterized by easy molding and coloring, simpleprocessing, none vulcanization and low consumption or energy. theleftover bits and pieces can be recovered. it is widely used inshoes making, adhesives, waterproof materials, modification ofhigher polymer and road bitumen, cable and toys. the annualcapacity 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 polymermodification: it can blend with pe,pp and ps to modify theirphysical 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 beused to produce all kinds of adhesive, especially hot-melt adhesivepressuresensitie, pressuresens-itive adhesive and solvent typeadhesive. they have advantages of high adhesion, poisonlessness andnone 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 canbe used to make vary kinds of leather shoes, travelling shoes andchildren’s shoes. they have comfortableness excellentandti-slipping, ventilating, and easy coloring. withoutvulcanization, sbs still has high strength, so the process ofshoe-making becomes simple. its leftover bits and pieces also canbe 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、卷材使用寿命的选择。
bitumen modification:the low temperature flexing and anti-flowing property at hightemperature of bitumen can be improved by adding 3% to 15%(wt%)sbs. hardening, embrittling and cracking at low temperature ofbitumen can be reduced due to improved flexing so as to extend theservice life of road and rolling material. softening and flowing ofbitumen at high temperature can be improved after the anti-flowingproperty is enhanced.
as the best choice forprolonging the service life of road and rolling materialeffectively, sbs modified bitumen is very popular in the developedcountries.
