Thermoplastic elastomers from reclaimed rubber and waste plastics

Abstract

Abstract Thermoplastic elastomeric compositions from reclaimed rubber and scrap plastics were prepared. The physical properties, dynamic mechanical properties, rheological behavior, and phase morphology of the blends were studied. A 50:50 rubber/plastic ratio was found to be the best for processability, ultimate elongation, and set properties. A sulfur‐accelerator system was found to be better than a peroxide system for dynamic crosslinking. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 83: 2035–2042, 2002
