The SBS type of “ABA” triblock copolymers, which has styrenic blocks on both ends of the molecule, will absorb the white oil and form a solid or semisolid clear rubbery material.

The Styrene-butadiene-styrene (SBS) Modified Asphalt

The styrene-butadiene-styrene (SBS) is a kind of thermoplastic elastomer which has the same elasticity with the rubber in normal temperature, and can be melt to flow at high temperature like plastics, called plastic material. Thus, the SBS modified asphalt is characterized as neither being viscous when being heated nor being fragile when cooled; of great plasticity and property of aging resistance. And the SBS modified asphalt is now the most successfully applied and widely used modified one. The amount of SBS added into the asphalt is normally between 5% ~ 10%. SBS is normally used in making not only waterproof membranes but also sealing material and waterproof paint.

Product Description:

CH401 is a linear block copolymer with 70,000-90,000 molecular weight, which also has 40% content styrene. It's widely applied to plastic modification and compounding, waterproof membranes and adhesive agent.

SBS is mainly used in four major fields: rubber products, resin modifiers, adhesives, and asphalt modifiers. In terms of rubber products, SBS molded products are mainly used in the shoe (sole) industry, while extruded products are mainly used for rubber hoses and tape; As a resin modifier, 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; SBS as an adhesive has the characteristics of high solid content, fast drying, and low temperature resistance; SBS, as a modifier for building asphalt and road asphalt, can significantly improve the weather resistance and load resistance of asphalt.

Asphalt modification
The application of SBS in asphalt modification includes two aspects: waterproofing membrane asphalt modification and road asphalt modification. The asphalt waterproofing membrane modified with SBS has the characteristics of good low-temperature flexibility, self-healing ability and durability, high-temperature flow resistance, aging resistance, thermal stability, and impact resistance. It can greatly improve the performance of the waterproofing membrane, extend its service life, and meet the needs of important buildings and structures. It has been widely used in municipal engineering, including bridge decks (concrete), subways, and underground passages, as well as in hydraulic engineering, including water tanks, canals, and so on.
Polymer modification
SBS is a good resin modifier that can be blended with resins such as PP, PE, PS, ABS, etc. to improve the impact resistance and flexibility of products. This type of product is commonly used in electrical components, automotive steering wheels, bumpers, seals, etc. Compared with developed countries and regions abroad, China's polymer modification industry is still in its infancy. In 2003, the consumption of SBS in polymer modification in China was approximately 16500 tons. With the development of China's automotive and home appliance industries, consumers' requirements for the comfort, safety, durability and other performance of goods will gradually increase. In addition, with the rapid development of China's synthetic resin industry, the domestic polymer modification industry will flourish.
Due to its excellent solubility, fast dissolution, good stability, and strong cohesion in hydrocarbon solvents, SBS avoids the harm to human health caused by the use of aromatic solvents. In addition, SBS adhesive has good elasticity, bonding strength, and low-temperature performance, low viscosity, and better creep resistance than general EVA and acrylic adhesives, making it widely used in daily life. It can be used in the production of shoe adhesives, metallurgical powder forming agents, laminating adhesives, wood quick drying adhesives, labels, adhesive tapes, disposable hygiene products, laminating adhesives, sealants, as well as for hooks, electronic components, general strong adhesives, versatile adhesives, and non drying adhesives.
Other fields
SBS can also be used as the main raw material for toys, furniture, and sports equipment; Used as flooring material, car seat cushion material, carpet substrate and sound insulation material, as well as wire and cable sheath. In addition, SBS can also be used for cement processing, automobile manufacturing, interior decoration of houses, and the manufacturing of various rubber hoses, such as bright oil, medical devices, household appliances, pipe strips, and wires and cables.

Styrene-butadiene-styrene and calcium carbonate nanoparticles were melt-blended with polystyrene for extrusion-foaming using supercritical carbon dioxide to simultaneously toughen and reinforce polystyrene foams.89 The cell structure was related to the system viscosity, by which toughening agent (SBS) also exerted a positive influence on foam quality in addition to nano-calcium carbonate which acted as nucleating agent.89 Styrene-butadiene block copolymer was used as toughening additive and talc as nucleating agent in production of poly(lactic acid) foam with supercritical nitrogen.80 The toughening additive acted as a nucleating agent due to which the amount of talc could be reduced.80 Polypropylene foam sheets containing impact modifier (Hytrel IM-1) were manufactured with excellent impact strength and low density, using supercritical carbon dioxide, for application in electronic packaging.90
