熱塑性丁橡膠SBS Styrene-butadiene thermoplastic elastomer SBS

 

熱塑性丁橡膠SBS外觀為白色或淺黃多孔圓條或圓片形小顆粒，兼有橡膠和塑料的優點，具有良好的耐低溫性、透氣性和抗濕滑性，易于加工成型。加工工藝簡單，無需硫化，能耗低，容易著色，邊角料可以回收。廣泛應用于制鞋、粘合劑、防水卷材、高聚物改性和道路瀝青改性、電纜、玩具等行業。

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:可以與聚乙烯、聚丙烯、聚乙烯等塑料共混改性，改善其物理性能，使其獲得更大范圍的應用。

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

粘合劑工業:SBS可用于生產各種類型的粘合劑，特別是熱熔壓敏型、壓敏型、溶劑型粘合劑，具有粘合力強、無毒、無環境污染等特點。

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.

制鞋工業:SBS可用于生產各種檔次的皮鞋、旅游鞋、童鞋，具有穿著舒適、抗濕滑、透氣性好、易著色等優點。由于SBS不需要硫化而具有很高的強力，使得制鞋工藝流程非常簡單，并具有邊角料可回收的優點。

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.

瀝青改性:在瀝青中加入3％—15％的SBS可改善瀝青的低溫屈撓性和高溫抗流動性能。改善瀝青的低溫屈撓性可減輕瀝青低溫下的發硬、發脆、龜裂，提高公路、卷材的使用壽命。改善瀝青的高溫抗流動性能可減輕瀝青在高溫下的軟化流淌。

SBS改性瀝青在發達國家應用非常普遍，是有效提高公路、卷材使用壽命的選擇。

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.
