SBS Description

SBS styrene thermoplastic elastomer, styrene-butadiene-styrene terpolymer, also known as thermoplastic styrene-butadiene block copolymer or thermoplastic styrene-butadiene rubber, referred to as SBS. According to the different methods of synthesis, SBS has a linear structure and a star structure. SBS for the white or yellowish porous round bars or flake-shaped particles, relative density 0.92 ~ 0.95. SBS has excellent tensile strength, elasticity and electrical properties, * small deformation, good flexural and resilience, high surface friction, SBS has excellent tensile strength, elasticity and electrical properties, small deformation, good flexural and resilience, and large surface friction. Because of the main chain contains double bonds cause sBs aging resistance is poor, in the high temperature air oxidation conditions, butadiene block will occur crosslinking, so that the hardness and viscosity increase. sBs soluble in toluene, methylene chloride, dichloroethane, etc., or with the solvent gasoline and other components of the mixture of solvents, insoluble in water, ethanol, solvent gasoline, ethyl acetate, acetone, cyclohexane, etc.

Product Application

SBS thermo plastic styrene butadiene rubber has many uses in adhesives, and can be used to produce contact adhesives instead of chloroprene - phenolic adhesives. Production of SBS grafting adhesive, or combined with neoprene rubber to produce CR-SBS mixed grafting adhesive; Manufacture ordinary shoe glue, shoe sole coating agent; Manufacture special adhesive for luggage; Production of solvent-based pressure sensitive agent, hot melt adhesive, hot melt pressure sensitive adhesive; Production of paper plastic film adhesive, polyolefin adhesive; Production of building glue, building sealant, CR-SBS sealant, waterproof coil special adhesive; Modified asphalt, etc.SBS is widely used in various industry applications such as footwear and compounds, modification of asphalt and plastics, adhesives, and so on. 1, SBS molded products mainly used for shoe (sole) industry. 2, extruded products are mainly used hose and tape. 3, as a resin modifier, a small amount of SBS were polypropylene (PP), polyethylene (PE), polystyrene (PS) Blend can significantly improve the low temperature properties of the article, and impact strength. 4, SBS as a binder with the characteristics of a high content of solids, fast drying, low temperature. 5, SBS as asphalt and road construction bitumen modifiers can be significantly improved weathering resistance and load performance of asphalt.
