Solution Partial Block SBR
Styrene-butadiene copolymers with tapered block monomer configuration, linear structure and very narrow molecular weight distribution. They are highly appreciated for their high purity, clear color and very low gel content. Due to the total styrene can be designed in a partial block content combined with a random domain of styrene and butadiene, these copolymers have excellent processability for mixing operations. Their structural characteristics permit also the applications in asphalt modification for road paving and polymer modified asphalt emulsion, formulation of adhesives, vulcanized rubber goods, footwear and impact modification for HIPS and ABS plastics.
The Solprene SBR product portfolio consists also of a range of rubber grades developed for the high performance tire segment. Composition variations and levels of functionalization are applied to meet and/or exceed the new tire labeling requirements. The polymer compositions include oil-extended SSBR, dry high vinyl SSBR and polar functionalized SSBR grades with commercial availability. Specific emphasis is given in performance criteria and maximizing the key “magic-triangle” properties of Rolling-Resistance, Wetgrip and Wear. Select grades are effectively used in other non-tire applications such as extruded and molded goods.
