抗氧剂是一种极为重要的塑料加工助剂,它可以使产品的寿命提高几倍甚至几十倍。目前,国外的抗氧剂研制和牛产情况均很活跃。以美国为例,抗氧剂生产厂家有五十个左右。1985年,美国塑料用抗氧剂达37.1百万磅,其中聚烯烃、苯乙烯树脂和ABS 共消费32.7百万磅,占总耗量的88%。 Antioxidant is a very important plastic processing aid, which can increase the life of the product by several times or even tens of times. At present, the development of anti-oxidants abroad and the situation of cattle production are very active. Taking the United States as an example, there are about 50 antioxidant manufacturers. In 1985, U.S. plastic antioxidants amounted to 37.1 million pounds, of which polyolefin, styrene resin and ABS consumed 32.7 million pounds, accounting for 88% of total consumption.
