Trinseo SPRINTAN™ SLR 4602 Solution Styrene Butadiene Rubber (S-SBR)
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE); Styrene Butadiene Rubber

Material Notes: Composition: SPRINTAN® SLR-4602 – 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-4602 – Schkopau is partially coupled and bears a GENERATION 2 functionalisation for improved polymer/filler interaction with carbon black as well as with silica. A non-staining stabiliser is added in the production.

Application: SPRINTAN® SLR-4602 – Schkopau provides outstanding wet grip/rolling resistance for fuel efficient tyre treads based on silica and/or carbon black. The high-vinyl micro structure makes SPRINTAN® SLR-4602 – Schkopau applicable in summer-, all-season-, as well as in winter tyres. The material can also be used in high-quality technical rubber articles.
