Polypropylene referred to as PP, is a relatively cheap plastic material, with good chemical resistance, heat resistance, high mechanical strength, good electrical insulation, environmental protection and recyclability. With the above advantages, suitable for large-scale production. However, PP plastic particles are easy to become brittle at low temperatures, long-term exposure to sunlight and the atmosphere is easy to age, resulting in reduced performance, low transparency, insufficient rigidity, poor dyeing, flammable, these shortcomings can be improved by using different additives to improve their performance and gradually optimize their performance.
