The automobile industry promotes the growth of demand for high-concentration polypropylene (HCPP), and there is huge room for domestic substitution in the Chinese market

Highly crystalline polypropylene (HCPP) is made from high isotactic polypropylene and added with a nucleating agent. It has the characteristics of high crystallinity, high rigidity, high surface hardness and high heat resistance. It is a high-end polypropylene product. With the continuous advancement of polypropylene development technology and the continuous improvement of downstream market requirements, HCPP has been developed and released. It has the characteristics of high melt index, high flexural modulus, high impact resistance, etc., and is expected to gradually replace the traditional high crystallinity Polypropylene.

According to the “In-depth Market Research and Development Prospects Forecast Report on China’s High Polypropylene (HCPP) Industry from 2023 to 2028” released by the Industrial Research Center shows that polypropylene tri-high materials can be widely used in electronics, communications, home appliances, automobiles, packaging, household products and other fields. In the automotive field, polypropylene tri-high materials can be used to manufacture pillars, bumpers, door panels, instrument panels and other components. my country is the world’s largest automobile producer. Against the background of increasing lightweight requirements for automobiles and the rising proportion of electric vehicle production, the proportion of engineering plastic applications continues to increase, driving the demand for polypropylene tri-high materials to continue to grow. At this stage, the automobile industry is the main driving force for the growth of my country’s polypropylene tri-high material market.

Highly crystalline polypropylene includes two categories: homopolymer HCPP and copolymer HCPP. Among copolymer HCPP products, heterogeneous copolymer HCPP is the third high material of polypropylene. Catalyst and polymerization technology are key factors affecting the performance of highly crystalline polypropylene. Taking the catalyst as an example, it needs to have characteristics such as high isotacticity, broad molecular weight distribution, high hydrogen sensitivity, high activity, and moderate porosity. In comparison, the technical barriers of homopolymer HCPP are relatively low, and the Chinese market has achieved localization at this stage; the technical barriers of copolymer HCPP are relatively higher, and my country’s market demand is highly dependent on external sources, especially for polypropylene three-high materials. The early market demand is mainly Rely on imports.

In the global market, the main manufacturers of polypropylene tri-ethylene materials include SK Chemicals, LyondellBasell, Korea Petrochemical, Hanwha Total Petrochemicals, Borealis, ExxonMobil, etc. Among them, SK Chemicals accounts for 10% of the global market share. than the highest. After continuous development, my country’s polypropylene tri-high material production strength has been continuously improved. At this stage, Yanshan Petrochemical, Maoming Petrochemical, Yangzi Petrochemical, Lanzhou Petrochemical, Guangzhou Petrochemical, Zhongsha Petrochemical, Zhenhai Refining and Chemical, etc. all have mass production capabilities, mainly PetroChina, Among the enterprises under Sinopec, Yanshan Petrochemical was the first to achieve large-scale production.

Industry analysts said that in 2017, my country’s demand for polypropylene tri-high materials was approximately 280,000 tons, and will grow by 2022 to 420,000 tons, with a compound annual growth rate of 8.5% during the period. At present, in my country’s polypropylene high-strength material market, imported products still occupy a large share. Many domestic manufacturers have average mass production capabilities, and product quality and output are difficult to compete with international advanced companies. Generally speaking, my country’s polypropylene tri-high material has broad application prospects, but there is still much room for improvement in the market’s localization rate.
