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.

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.

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.

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.
