摘要: Abstract The effect of various degradations on the tensile and morphological properties polypropylene (PP)/natural rubber (NR) PP/recycle (RR) blends at different content were studied. melt mixed using a Brabender Plasticorder torque rheometer 190°C 50 rpm. All exposed three conditions, i.e., heated in oven (100°C) for 24 hrs, immersed distilled water (90°C) ASTM oil No. 3 70 hrs. results indicated that similar degradation condition, PP/RR exhibit higher percentage retention strength Young's modulus but lower elongation break than PP/NR blends. Scanning electron microscopy (SEM) examination fracture surface indicates smooth after thermo-oxidative aging. This observation supports aging ble...
