SBS - Styrene butadiene
SBS - Styrene butadiene styrene styrene butadiene styrene.
Application: Components for the automotive industry i.a. bellows for brake amplifiers, radiator hoses and bulkhead bushings from cabin to engine compartment, wheels and profiles for vacuum cleaners medical articles, sports and leisure, toys, electronics and bellows for covering connections between electrical appliances. Used for soft items in industry and in cars where vulcanized rubber was used before. Used for non-slip handles on hand tools Roofing materials together with asphalt and fiberglass.
Compounding and dyeing options: TPE can be compounded with fillers, minerals, flame retardants and various reinforcement materials. However, TPE can be dyed with certain limitations due to its own color.
Dipping: For small series and workpieces suitable for dipping, this manufacturing method can be used to advantage. The tooling costs associated with dipping are small.
Colors: Opal white. SBS can be stained with certain limitations due to its own color.
Processing processes: SBS can be processed by injection molding, extrusion, blow molding, rotational molding and thermoforming.
Trade names: Dryflex. / Roofing materials = DynaPly® - DynaKap® - FR. - DynaMax ™ - Dyna Glas® 30 FR
History: In 1961, Shell Chemical Co. developed the first styrene-butadiene-styrene (SBS) polymer. In 1970, a French company introduced the first asphalt roof membrane reinforced with SBS.
Category: Thermoplastic elastomer (TPE).
Chemical resistance: Not resistant to persistent exposure to oil and grease. Thermoplastic materials generally have properties on a par with rubber. Some materials have even better resistance to oil and petroleum based liquids.
Chemical structure: TPE-S: Styrene block copolymers with the starting monomers styrene, butadiene and ethylene. Density in kg / m3 = 900 -1200
Mechanical properties: Can be cast as soft as down to Shore 10A and up to a hardness of Shore 60D. General properties at the level of rubber.
Injection molding: Simpler manufacturing process than with rubber, but higher tool costs.
Welding: Heating mirror Thermal Properties. Application from -50 to 60º C.
UV Stability: Rings
Thermoforming: Excellent.
