The market demand for high-impact polypropylene (HIPP) is increasingly strong, and the multi-stage reactor preparation method is its main preparation method.

High impact polypropylene (HIPP) refers to a modified polypropylene material made by adding modifiers such as polymer elastomers to polypropylene resin (PP) using chemical or physical modification methods. High-impact polypropylene has the advantages of good impact resistance, good toughness, low temperature resistance, and high modulus. It is widely used in household appliances, automobile manufacturing, pipes and other fields.

The main preparation methods of high-impact polypropylene include multi-stage reactor preparation method and blending modification method. The multi-stage reactor preparation method is the mainstream preparation method of high-impact polypropylene. This method has the advantages of less by-products, stable reaction, high raw material utilization rate, and easy parameter control, and is suitable for continuous production; the blending modification method refers to Polypropylene resin and polymer elastomers such as EPDM rubber, EPDM rubber, powder rubber and polyolefin elastomer are used as raw materials, and the finished product is obtained by physical blending.

High-impact polypropylene is widely used in household appliances, automobile manufacturing, pipes and other fields. In the field of household appliances, high-impact polypropylene can be used to produce casings for refrigerators, washing machines, televisions, vacuum cleaners, air conditioners and other appliances; in the field of automobile manufacturing, high-impact polypropylene can be used to make car power battery casings and car bumpers. , automobile chokes and automobile interior and exterior trim parts, etc.; in the field of pipes, high-impact polypropylene can be used to manufacture chemical pipelines, highway drainage pipes, etc. According to the “2023-2028 China High Impact Polypropylene (HIPP) Industry Market In-depth Research and Development Prospects Forecast Report span>》shows that as the scope of applications continues to expand, my country’s high-impact polypropylene market demand is increasingly strong, and its demand will increase by nearly 15% year-on-year in 2022.

The global high-impact polypropylene industry is highly concentrated. Representative companies are mainly concentrated in Europe, the United States, Japan and South Korea, including Exxon Mobil in the United States, Lyondellbasell in the Netherlands, SK Group in South Korea, South Korea’s LG Chemical Company, South Korea’s Samsung Chemical Company (SAMSUNG), Japan’s Sumitomo Chemical Co., Ltd. (SUMITOMO), Japan Polypropylene Co., Ltd. (JPP), etc. ExxonMobil is the world’s largest producer of high-impact polypropylene, and its high-impact copolymer UV-resistant polypropylene can be used to make automotive dashboards.

In the local market, there are many high-impact polypropylene manufacturers in my country, and the market competition is fierce. Qilu Petrochemical, Jusailong, Guangzhou Petrochemical, Weixing New Materials, Zhongjing Petrochemical, Yueyang Xingchang, Huajin Group, etc. are the main manufacturers of high impact polypropylene in my country.

Industry analysts said that high-impact polypropylene, as a modified polypropylene, has a wide range of uses and has good industry development prospects. In the early stages of industry development, my country’s high-end high-impact polypropylene mainly relied on imports due to factors such as high technical barriers and high raw material prices. In recent years, Chinese companies have continued to increase the improvement of high-impact polypropylene production technology, driving the industry to gradually develop in the direction of high quality.
