PP is easy to break and degrade under the action of light and heat. PP without stabilizer will become brittle when heated for more than half an hour at 150 C or exposed to sunshine for 12 days. PP powder without stabilizer will degrade seriously in indoor shelter for 4 months and emit obvious acid taste. Adding more than 0.2% antioxidant before granulation of PP powder can effectively prevent the degradation and aging of PP in the process of processing and use. Antioxidants can be divided into two categories: free radical chain reaction terminators, also known as main antioxidants and peroxide decomposition agents, also known as auxiliary antioxidants. Rational combination of main and auxiliary antioxidants will play a good synergistic effect. After leaving the die, if PP is cooled slowly in air, larger grains will be formed and the transparency of the product is low. If the film is quenched in water as follows, the molecule movement of PP is frozen rapidly and the crystal can not be formed, then the film is completely transparent. The shrinkage rate of PP is larger than that of ABS plastics, reaching over 2%, which is much larger than that of ABS plastics by 0.5%.
