SBS thermoplastic styrene Introduction SBS (English name: Thermoplastic SBS elastomer) belong styrenic thermoplastic elastomers, styrene - butadiene - styrene tri-block copolymers (Styrene Butadiene styrene block polymer), known as thermoplastic styrene-butadiene block copolymer or a thermoplastic rubber, referred to as SBS. SBS excellent performance of both rubber and plastics, with good flexibility, low temperature resistance, air permeability, resistance to temperature slip resistance, coloring, electrical insulation, processing without curing, can be directly used injection molding, molding, extrusion, etc. various molding process. The main purpose and characteristics are widely used in asphalt modification, footwear, plastic modification and adhesives industry. Polymer modified: with polyethylene, polypropylene, polystyrene and other plastics modification, to improve its physical properties, so that they get a wider range of applications. Adhesives industries: SBS can be used for production of various types of adhesives, especially hot melt pressure-sensitive, pressure-sensitive, solvent-based adhesive with strong adhesion, non-toxic, pollution-free characteristics of the system Footwear Industry: SBS can be used for production of various grades of leather shoes, hiking shoes, children's shoes, with a comfortable, anti-slippery, breathable, easy to color, etc., due to the SBS process is very simple and does not require curing, and can have a scrap recycling advantages. Asphalt Modified: 3% -15% of SBS in the asphalt to improve low-temperature flexibility and high resistance to the flow properties of asphalt. Improve low-temperature asphalt relieve stiff flex life of asphalt at low temperatures. Improve the anti-high-temperature flow properties of asphalt bitumen at high temperatures can reduce the softening flowing. SBS is effective in improving the highway, roll life. Recommended processing formula (1) with a dry adhesive soles basic recipe (amount are parts by weight) of pure rubber oil CaCO3 PS ordinary white carbon black additives antioxidants 100 70 30 30 ≤5 ≤2 1 translucent 100,703 -5153-521 transparent 10045-500002-3 appropriate amount of technical points: the mixing process is the key, the process temperature generally feed section 140 ℃ -150 ℃, the compression section 150 ℃ -170 ℃, both of segment 160 ℃ -180 ℃, die 140 ℃ -150 ℃. Transparent material to consider adding 3-5 servings K resin and the amount of UV absorbers. Reference formula: filled with oil, resins, fillers, protectant, release agents, coloring agents, blowing agents (2) the use of SBS modified bitumen dosage: road bitumen (4% -6% by weight) Construction Asphalt Modified ( 8% -12% by weight) conditions: We recommend the use of colloid bodies and other special machinery, the temperature is about 180 ℃ (3) SBS adhesive SBS presents a two-phase separation structure, with a with a good soluble and self-reinforcing, You can add a variety of auxiliary components, preparation of various, high-performance adhesives, such as: adhesive, adhesive, hot melt and so on.
