Product Description

Product Description:

SBS thermoplastic elastomer:  is styrene - butadiene - styrene three segment copolymer, also known as thermoplastic styrene butadiene styrene block copolymer or thermoplastic, referred to as SBS. After heating the material can flow, easy processing molding . After cooling to room temperature, the polystyrene segments aggregate into a glassy microdomain, which acts as a physical cross-linking point for the polybutadiene segments, thereby rendering the material behaving as rubber. So called "thermoplastic elastomer". Depending on the synthesis method, the SBS has a linear structure and a star structure.
Appearance: SBS is white or yellowish porous round or disk-shaped particles, the relative density of 0.92 to 0.95.

SBS has excellent tensile strength, elasticity and electrical properties, permanent deformation is small, good flexion and rebound, the surface friction. But the SBS anti-aging is poor.

SBS products Application :  

Uses: As a new type of synthetic polymer materials, SBS has many uses. At present, mainly for the footwear industry, plastics, asphalt modified, adhesive industry and the production of a variety of rubber products.
1. Adhesive industry: can produce all types of adhesives, especially hot-melt pressure-sensitive, pressure-sensitive, solvent-based adhesive, with strong adhesion, non-toxic, no environmental pollution and so on.
2. Coating ink: SBS, the production of paint, ink in some areas have better performance, such as coating surface elasticity, coating low temperature performance, the rubber substrate better adhesion, but also can The production of low temperature transparent oil.
3. Footwear industry: SBS can be used as soles and shoes upper, you can also produce light-colored soles.
4. Plastic Modification: It can be blended with PE, PP, HIPS and other plastics to improve its physical properties (to improve the impact strength), so that they get a larger range should be.
5. Asphalt modified: SBS modified asphalt after the winter to overcome the shortcomings of soft summer, both for the laying and repair of highways, can also produce excellent quality waterproof insulation.
