Abstract

This investigation focuses on understanding the effects of particle size and surface area of cryogenically-ground micronized rubber powders (MRP) on the properties of MRP/polypropylene (PP) composites. Comparisons are made with ambient-ground rubber powders and its PP composites. The morphology of the fracture surfaces of the composites is studied in relation to the effects of particle size on mechanical properties. In addition, this paper discusses utilizing a compatibilizer with MRP in improving the mechanical performance of the PP composites for its use in various market segments, such as automotive, consumer and, construction.
