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.
Category: SBS
Model: YH-791E (1301E)
Usage: YH-791E is widely used in asphalt modification, shoe making, plastic modification, adhesive and other industries.
Performance characteristics: SBS has both excellent properties of rubber and plastic, with good elasticity, low temperature resistance, air permeability, temperature sliding resistance, coloring and electrical insulation. It does not need vulcanization during processing, and can be directly formed by injection molding, molding, extrusion and other processing methods.
