Eco-thermoplastic Elastomer Blends Developed by Compatibilizing Chlorinated Polyethylene into Industrial-Waste-Filled Polypropylene/Acrylonitrile Butadiene Rubber System

Eco-thermoplastic elastomer blends based on industrial-waste-filled polypropylene (PP) and acrylonitrile butadiene rubbers (NBRs) were prepared by melt mixing with blends being exclusive consideration on the blend ratio and compatibilized with chlorinated polyethylene (CPE). The use of compatibilizer based on polyolefins is a significant approach for the preparation of blends with marked dissimilarities in terms of chemical structure between their constituents. The exploit of CPE improved the compatibility between the PP and NBR in the presence of industrial waste, such as marble waste (MW) and mixing torque, mechanical and aging properties of the resultant blends compared well with those of uncompatibilized MW- filled PP/NBR blends. Exceptional mechanical performance, particularly tensile strength, modulus tear strength and better elongation at break (lower values) and improved aging resistance were obtained with the compatibilization, but the performance of blends was inferior to that observed for uncompatibilized blends.
