Buna® SL 4525-0 is a copolymer of butadiene and styrene containing 25% of bounded styrene. It is produced by solution polymerization process using an alkyl-lithium initiator. The low vinyl content provides a low Tg which gives an excellent low temperature flexibility, abrasion resistance and low rolling resistance. Corresponding vulcanizates of this product have superior resistance to reversion. The polymer is stabilized with non-staining antioxidants. Buna® SL 4525-0 has excellent properties in the manufacture of tires, retreads, moulded technical parts, injected or extruded goods, surgical goods, shoe soles and automotive industry parts. In tire manufacture it is blended with NR, BR or E-SBR.
