Performance Enhancing Crosslinked SBR Masterbatches for Thermoplastic Elastomers

摘要

Masterbatches of crosslinked solution-polymerized styrene-butadiene random elastomers (XL-SBR) and polypropylene (PP) were prepared and used for enhancing the oil resistance, compression stress relaxation performance, lowering gloss, and compression set of styrene-ethylene/butylene-styrene (SEBS)-based thermoplastic elastomer (TPE) compounds. Enhanced performance was achieved when SBR partly or substantially replaced the SEES component. Modification of SEES compounds in the Shore A range of 45-85 with the crosslinked SBR is discussed.
