| Composition: SPRINTAN® SLR-4630 – 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 medium styrene/high vinyl micro structure and a typical glass transition temperature of -29°C. SPRINTAN® SLR-4630 – Schkopau is partially Si-coupled and contains a non-staining stabiliser. Application: SPRINTAN® SLR-4630 – Schkopau provides an excellent balance between good wet traction and low rolling resistance for silica- and/or carbon black- filled tyre tread compounds for summer -, winter -, and all season tyres. The product can also be used in high-quality technical rubber articles. Test Formulation (based on IRB7 black): - Polymer – 137.5 parts by mass
