There are many high-rigidity polypropylene (HSPP) manufacturers in my country, but high-melt HSPP is completely dependent on imports.

Polypropylene is a thermoplastic resin. The melt index (MI) is one of the most important indicators that affects the processing performance of polypropylene. The larger the MI, the better the melt flow properties of the polypropylene resin. High rigidity polypropylene (HSPP for short) is a type of polypropylene material selected based on its performance characteristics. The main difference between HSPP materials and HCPP materials lies in the Izod impact strength parameter. An HSPP material with an Izod impact strength parameter of 50 has an MI greater than 10g/10min and a flexural modulus greater than 1100MPa.

In recent years, my country’s polypropylene production capacity has expanded rapidly. At this stage, my country has become a major producer of polypropylene in the world. In 2020, my country’s new polypropylene production capacity will reach 4.4 million tons/year, and the total production capacity will be close to 33 million tons/year. my country’s polypropylene industry has a structural oversupply problem. Among them, mid- and low-end polypropylene has overcapacity and fierce market competition. High-end polypropylene still relies on imports. Under fierce market competition, high-end polypropylene has become a new breakthrough for many domestic companies, and HSPP is one of them.

As a high-grade polypropylene special material, HSPP improves the toughness of the modified material and simplifies its formula. At the same time, HSPP has the characteristics of high impact strength and high rigidity. In recent years, with the high-quality development of my country’s economy, the market demand for HSPP has increased. Keep releasing. At this stage, HSPP is mainly used in automobiles, home appliances, toys and other fields. Automobiles are the largest application scenario of HSPP, accounting for 51.6%, followed by toys, accounting for 30.4%. The two major fields have a combined market share. More than 80.0%.

According to the “2021-2026 High Stiffness Polypropylene (HSPP) Industry Market In-depth Research and Investment Prospects Forecast Analysis Report>> shows that according to different melt index MI values, HSPP can be divided into low melt index HSPP products, medium melt index HSPP products, and high melt index HSPP products. Polypropylene raw materials with high MI values ​​are more conducive to low-temperature extrusion. There are a large number of HSPP product manufacturers in my country, but they mainly produce medium and low melt index HSPP products, while high melt index HSPP products (MI>30) are completely dependent on imports.

At this stage, the demand for HSPP in my country’s market is about 420,000 tons/year. As automobiles develop towards lightweight and high-performance, and market demand upgrades, the HSPP market demand will maintain a growth trend. At present, the supply of medium and low melt index HSPP products in my country is in a situation of overcapacity. The domestic suppliers are mainly Qilu Petrochemical, Formosa Plastics Ningbo and Yanshan Petrochemical. High melt index HSPP products rely on imports, and demand mainly comes from Borouge, Lyondellbasell and Exxonmobil companies.

Industry analysts said that high-rigidity polypropylene is a high-grade polypropylene special material. At this stage, my country already has medium-low melting It refers to the production capacity of HSPP and the market is oversupplied, but high melt refers to HSPP still relying on imports. In this context, Chinese companies still need to increase relevant technology research and development, strengthen basic research on HSPP materials and personnel training, form a series of HSPP products, and at the same time improve the supply capacity of high-melt index HSPP to promote the sustainable development of the polypropylene industry.
