Influence of Zinc Oxide Contents on Mechanical, Rheological and Thermal Properties of Thermoplastic Natural Rubber

Article Preview

Abstract:

The influence of ZnO contents on properties of the natural rubber/polypropylene thermoplastic vulcanizates (NR/PP TPVs) is investigated. The NR/PP TPVs with ZnO obviously show improvement of mechanical, rheological and thermal properties comparing to the TPV without ZnO addition. The ZnO content does not much affect on mechanical and rheological properties of the TPVs. However, it strongly influences on thermal property especially decomposition temperatures at 5 and 50 %wt loss of polymer (Td5 and Td50) and onset decomposition temperature of rubber phase (Tronset).
