Abstract
Thermal-oxidative aging properties of high temperature resisitant polypropylene (PP) were investigated by crazing time.The effects of composition of PP,antioxidant,and black pigment on thermal-oxidative aging properties were illustrated.The results showed that there existed difference in different high temperature resistant PP of which crazing time were obviously influenced by various factors such as composition,antioxidant,and black masterbatch or powder.Additional antioxidant could significantly increased crazing time of materials,which improved their thermal-oxidative aging properties.When the combition of antioxidant and black pigment,the former played a leading role in thermal-oxidative aging properties at the low temperature but the latter had a significant effect at the high temperature.关键词
