According to the statistics of Soma.com, in 2021, China plans to put 11 sets of polypropylene plants into production, increasing the scale by 3.3 million tons. By the end of 2021, China has built 36.09 million tons of polypropylene, with a single largest polypropylene plant of 450000 tons/year. In 2022, China plans to put 17 sets of polypropylene units into production, involving a scale of 5.8 million tons/year. 

At present, Zhejiang Petrochemical and Haiding New Materials have completed putting into production. At the same time, China’s main polypropylene supply provinces and cities include Zhejiang, Guangdong, Shandong, Liaoning and Shaanxi. Enterprises with large capacity scale include Zhejiang Petrochemical, National Energy Group Ningmei, Donghua Energy, Yanchang Zhongmei Yulin Energy Chemical, Hengli Petrochemical, Sino Korea Petrochemical, etc.

The mainstream development directions of domestic polypropylene specialty materials include automobiles, home appliances, medical syringes, medical infusion bags, medical care pads, medical protective clothing, medical consumables, home decoration building materials, household storage, food and drug packaging, electronic packaging materials, etc.

It can be seen from the figure above that in 2021, the main direction of research and development of downstream high-end brands of polypropylene will be in the packaging field. In the field of high-end polypropylene for packaging, the main applications of research and development will be packaging polypropylene for cooking film, metallocene random polypropylene for electronic clean packaging, terpolymer milk tea cup polypropylene, special polypropylene for matting film modification, high impact and ultra permeable polypropylene, etc. 

The second place is in the automotive field, accounting for about 24% of the total number of brands. With the upgrading of the automotive industry, it has gradually expanded. For example, it was only used in the interior and front and rear bumpers before, but now it has gradually expanded to the internal buffer module, dashboard, door handle, impact vane, engine internal components, etc.
