Material Notes:
Composition: SPRINTAN® SLR-4601 – Schkopau is manufactured by anionic solution polymerization using an organo-lithium initiator. The product has a medium styrene/high vinyl micro structure and a typical glass transition temperature of -25°C. SPRINTAN® SLR-4601 – Schkopau is partially coupled and bears a GENERATION 1 functionalisation for improved polymer/filler interaction especially with carbon black. A non-staining stabilizer is added in the production.Application: SPRINTAN® SLR-4601 – Schkopau provides excellent balance between wet grip and rolling resistance for low fuel consumption tyre treads based on carbon black. The high-vinyl micro structure makes SPRINTAN® SLR-4601 – Schkopau applicable in summer-, all-season-, as well as in winter tyres.
