Solprene 303 is a linear random-block styrene-butadiene copolymer with 46% styrene content, 11% present as a polystyrene block.Solprene 303 is used in vulcanized microcellular shoe soles; it provides hardness and can be combined with inorganic fillers using high concentration of them with good dispersion in compounding. It can be blended with other rubbers to reduce die swell and increase processability in extruded and molded goods by compression.It can replace E-SBR 1009 and 1018 types.
