1433 is a linear random-block styrene/butadiene copolymer having 45% of styrene content, 33% present as a polystyrene block.

1433 is a SSBR copolymer that provides low shrinkage and dimensional uniformity at the final product in vulcanized compounds. It also maintains an excellent balance of high hardness and oil absorption; therefore it is possible to increase the extender oil in formulation to reduce costs without losing in quality and properties.

It is a polymer of high purity, essentially free of gel and with a light color and has a non-staining antioxidant system.
