摘　　要：氧化诱导期和长期热稳定性,是表征塑料材料或制品耐热、耐氧化的两项重要数据。使用适当、适量的抗氧剂,可以有效提高塑料材料和制品的氧化诱导期或长期热稳定性。氧化诱导期和长期热稳定性没有必然的线性对应关系,设计配方时需以试验为依据。Oxidation induction period and long-term thermal stability are two important datas to characterize the heat resistance and oxidation resistance of plastic materials or products. Proper antioxidants can effectively improve the oxidation induction period or long-term thermal stability of plastic materials and products. Since there is no necessary linear correspondence between oxidation induction period and long-term thermal stability, the formula design should be based on experiments.

关 键 词：塑料材料和制品 氧化诱导期 长期热稳定性 抗氧剂
