SBS
| COMMODITY | GRADE | APPLICATION | ORIGIN/ Maker | TYPE |
| SBS (Styrene Butadiene Styrene block polymer) | Injection (injection) grade foaming grade adhesive grade extrusion grade Relative molecular mass The linear SBS has an average molecular weight of 80,000 to 120,000, and the star SBS has an average molecular weight of 140,000 to 300,000 |
Relative density: 0.92～0.95 Function: It has excellent tensile strength, elasticity and electrical properties, small elastic deformation, good flexion and resilience, and large surface friction. Oxygen-resistant, oxygen-resistant, similar to horizontal and styrene butadiene rubber chains. Breathability Because the main bond makes SBS resistant to aging, under the oxidizing condition of outdoor air, the other kind will crosslink, which will increase the hardness and viscosity. △Rubber Products: The molding method is mainly used in the shoe (sole) industry, and the extrusion method is mainly used in hoses and tapes. △Resin modification: Blending a small amount of SBS with polypropylene (PP), polyethylene (PE), and polystyrene (PS) can significantly improve the low-temperature performance and impact strength of the product. △Adhesive: As an adhesive, SBS has the characteristics of high solid content, fast drying, and low temperature resistance. △Asphalt modifier: As a modifier of construction asphalt and road asphalt, SBS can significantly improve the weather resistance and load resistance of asphalt. △SBS can also be used for toys, furniture and sports equipment; as floor materials, car seat cushion materials, and sound insulation materials, and wire and cable sheaths. |
