[Industry Reports]：What are the main research and development directions of domestic Polypropylene Market in 2021?

at present, polypropylene is mainly used in the fields of automobiles, household appliances, injector for medical purpose, medical infusion bags, medical nursing pads, medical protective clothing, medical consumables, interior decoration material, daily household storage, food and drug packaging, electronic packaging material, etc, the following figure shows the market application.

According to the application statistics of the research and development direction of major Chinese polypropylene enterprises in 2021in the above figure, it can be seen that, the main direction of research and development of the downstream high-end brand of polypropylene in China in 2021is packaging collar domain, in the field of high-end polypropylene for packaging, the main applications of research and development include packaging polypropylene for cooking film, electronic clean packaging metallocene random polypropylene, ternary copolymer milky tea cup polypropylene, Matt film modification special material polypropylene, high impact resistance ultra-transparent polypropylene, etc.

The second place is polypropylene for automobiles., the number of high-end brands developed in 2021accounted for about 24% of the total number of brands, and gradually expanded with the upgrading of the automobile industry. For example, it was only used in interior trim and front and rear bumper before, at present, it has gradually expanded to internal buffer modules, dashboards, door handles, impact Fender, engine internal components, etc. According to the survey, in 2021, polypropylene enterprises invested in the research and development of polypropylene for automobiles. The main direction lies in car expansion kettle metallocene polypropylene, bead foam polypropylene, high-flow ultra-high impact resistance low warpage polypropylene, high melt finger high impact resistance copolymer, the fourth generation of high rigid polypropylene foam material, hydrogen adjustment method high impact copolymer polypropylene, etc.

according to the number of high-end polypropylene brands studied by China's polypropylene enterprises in 2021, Maoming Petrochemical is the enterprise that has the most active research on high-end brands, the largest investment and the largest research and development of new brands in China's polypropylene in 2021, it is conservatively estimated that 13 polypropylene grades have been deeply studied and good progress has been made. Yanshan Petrochemical ranked second in the R & D investment in Polypropylene Industry. Yanshan Petrochemical conservatively estimated the R & D of 9 grades of polypropylene in 2021, over the years, Yanshan Petrochemical Company has mainly conducted in-depth investigation and research on metallocene polypropylene, and is in a leading position in the domestic technical field of metallocene polypropylene.

Research on new brands of major domestic polypropylene enterprises in 2021

the main research and development direction of polypropylene enterprises reflects the investment strength of enterprises in the field of new polypropylene brands and the differences between enterprises in their views on the future application prospect of polypropylene. For example, the research and development of private enterprises mainly focuses on the fields of ordinary household polypropylene and packaging polypropylene, while the research and development direction of polypropylene of Sinopec, PetroChina and other enterprises focuses on the special material polypropylene, for example, high solubility refers to polypropylene, Metallocene polypropylene, three-high polypropylene, polypropylene for vehicles, etc.

Summary of Research and development directions of major domestic polypropylene enterprises

according to statistics, although the total number of brands invested by Chinese polypropylene enterprises in research and development of high-end polypropylene was close to 130 in 2021, the production of the top 5 brands accounted for about 47% of the total output, nearly half. In other words, most of the high-end brand polypropylene mainly developed in China in 2021 is still small-scale polypropylene with small production volume. Although this high-end brand polypropylene has been put into the market, the overall market volume has not been enlarged. Among them, CPP special material HP550J is the high-end brand of polypropylene with the largest production scale in 2021, with a total production of more than 320,000 tons. The second is homogeneous injection molding HP500N, which produced more than 200,000 tons in 2021.
