PP Sinopec Maoming K8303 features high impact resistance

In 1954, G. Natta first polymerized propylene into polypropylene (using chloride of aluminum and titanium as catalyst), and established the theory of directional polymerization, which attracted people's attention. [4]

In 1957, Montecatini company of Italy and Hecules company of the United States established polypropylene production units of 6000T /a and 9000T /a respectively. [4]

In the late 1960s to the mid 1970s, polypropylene entered a period of great development. [4]

Since 1980s, the yield of polypropylene has been in the forefront of synthetic resins, and it is now only lower than polyethylene, ranking the second. [4]

China began to study the process of polypropylene production in 1962. [4] Since the 1980s, polypropylene has developed rapidly in China. China has introduced some advanced polypropylene production technology and production equipment, has established a number of large and medium-sized polypropylene production facilities in Yanshan, Yangzi, Liaoyang and other places, also built a large number of small bulk polypropylene production facilities, and to alleviate the contradiction between supply and demand has played a certain role. With the large increase of production scale, the production of polypropylene resin in China has entered a stage of rapid development [7]. In 2012, China's PP production capacity reached 12.967 million tons. [8] In 2015, The production capacity of PP in China was 20.13 million tons/year. [9]

PP Sinopec Maoming K8303 supply and demand status

Due to the large gap between supply and demand of polypropylene in China, most new large-scale refining, ethylene cogeneration projects and coal olefin projects have been equipped with polypropylene units in recent years. Therefore, China's polypropylene capacity will increase significantly in the future. At the same time, it is also necessary to consider those small backward polypropylene installation technology, especially the intermittent small body device will be phased out, it is estimated that the production capacity of polypropylene in China will reach a higher level by 2025. With the rapid development of China's economy, the demand for various chemical raw materials is increasing, resulting in the highest consumption of polypropylene in history, so China will become the world's largest polypropylene consumer country. In 2003, the consumption of polypropylene in China has reached 5.32 million tons; It was the first to reach 10 million tons in 2007; In 2008, due to the impact of the financial crisis, it decreased slightly to 10.79 million tons; Currently (2018), it has grown to 12.32 million tonnes, driven by infrastructure investment and domestic demand.
