Styron Sprintan® SLR 6430 Solution Styrene Butadiene Rubber (S-SBR)

Composition: SPRINTAN® SLR-6430 – Schkopau is manufactured by anionic solution polymerization using an organo-lithium initiator. In relation to solid rubber the grade is extended with 37.5 parts of TDAE oil which complies with the EU Directive 2005/69/EC for use in tyre application. The product has a high styrene/medium vinyl micro structure and a typical glass transition temperature of -36°C. SPRINTAN® SLR-6430 – Schkopau is partially Si-coupled and contains a non-staining stabilizer.Application: SPRINTAN® SLR-6430 – Schkopau provides high wet grip, improved wear & handling properties combined with excellent low rolling resistance for high performance tyre treads. The product can also be used in high-quality technical rubber articles.
