Thermoplastic Elastomers Based on Ethylene-vinyl Acetate Copolymer and Waste Nitrile Butadiene Rubber Powder Blends Compatibilized by Chlorinated Polyethylene

ABSTRACT

Thermoplastic elastomers (TPEs) based on ethylene-vinyl acetate (EVA)/waste nitrile butadiene rubber powder (WNBRP) blends compatibilized by chlorinated polyethylene (CPE) were prepared by melt-compounding. The tensile strength and the elongation at break of the EVA/CPE/WNBRP blends were increased significantly compared with those of the EVA/WNBRP blends. The fracture surfaces of the EVA/CPE/WNBRP blends were smooth; moreover, the WNBRP in the etched EVA/CPE/WNBRP blends were inserted in the EVA matrix tightly. DMA results revealed that when the CPE dosage was 5 phr in the EVA/CPE/WNBRP blend, the Payne effect was weakened significantly.
