The pace of structural adjustment of the polypropylene industry has accelerated, and the production capacity of copolymerized polypropylene has steadily increased.

Polypropylene (PP) is a polymer formed by the addition polymerization reaction of propylene. It has a transparent and light appearance. According to different polymerization methods, polypropylene can be divided into homopolymerized polypropylene and copolymerized polypropylene. Copolymerized polypropylene has the characteristics of high strength, high rigidity, and excellent processing performance, and is the base material for high-end polypropylene special materials. In recent years, as the industrial structure continues to be optimized and production technology becomes more mature, more and more chemical companies have entered the copolymer polypropylene market. Against this background, my country’s copolymer polypropylene production capacity has increased year by year.

Copolymerized polypropylene is further divided into random copolymerized polypropylene and impact copolymerized polypropylene. Melt index (MI) is a representative indicator of polypropylene performance. As the melt index increases, the melt fluidity of polypropylene becomes better, and vice versa. According to different MI, impact copolymerized polypropylene can be divided into high melting impact copolymerized polypropylene, medium melting impact copolymerized polypropylene and low melting impact copolymerized polypropylene. Among them, medium and high melting impact copolymerized polypropylene are mainly used in auto parts and home appliance casings. , turnover boxes and other fields, low-melt impact-resistant copolymer polypropylene is mainly used in battery casings, home appliance casings and daily necessities.

According to the “2021-2026 China Copolymer Polypropylene Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, In recent years, with the upgrade of market demand and the advancement of process technology, the production capacity of impact copolymerized polypropylene has expanded rapidly, especially low-melt impact copolymerized polypropylene. In 2020, the production capacity of low-melt impact copolymerized polypropylene will be about 12 million tons. With the relevant production capacity under construction put into operation, it is expected that the production capacity of low-melt impact copolypropylene will reach about 13.2 million tons in 2021.

In terms of copolymerized polypropylene, there are many related domestic manufacturers, including Donghua Energy, Shenhua Group, Ningbo Formosa Plastics, Yanshan Petrochemical, Hongji Petrochemical, Dawn Co., Ltd., Sinopec, PetroChina, etc. With the increase in the number of companies involved, the copolymer polypropylene market supply will gradually become abundant. At the same time, the copolymer polypropylene market competition will further intensify.

my country is one of the countries with the most comprehensive application of polypropylene production technology in the world. In recent years, with the continuous optimization of production technology, my country’s polypropylene production capacity has expanded rapidly. At this stage, my country has become a global polypropylene producer. At present, homopolymerized polypropylene is still the mainstream product in the market, and copolymerized polypropylene has great potential for market development. In the future, as domestic polypropylene production capacity increases, polypropylene’s external dependence will continue to decline. It is expected that my country’s polypropylene external dependence will drop to 4.2% in 2030.

Industry analysts said that my country is the world’s major producer of polypropylene. In recent years, with the continuous optimization of production processes, the polypropylene industry has The pace of structural adjustment is accelerating, and copolymer polypropylene has become an important choice for many enterprises to adjust their structure. Copolymerized polypropylene has a wide range of applications. With the release of downstream market demand and the commissioning of related production capacity under construction and planned, the scale of the copolymerized polypropylene industry will further expand in the future.
