Significant progress in localization of medical materials

Release time:

2024-07-29

It is of great significance to maintain the security and stability of the industrial chain supply chain and enhance the core competitiveness of domestic high-end new materials.

Product Name:PMP (poly -4-methyl -1-pentene)

Product use:PMP is a high-end functional polymer material, with low density, high melting point, excellent oxygen permeability and safety and non-toxic characteristics, in the field of high-end medical and electronic products have important uses, can produce "artificial lung" (ECMO) lung membrane and 5G communication high-frequency insulators and other products.

Market conditions:The oxygen transmission rate of PMP is extremely high, which is more than 10 times that of polypropylene (PP), and gradually replaces PP as the main substrate of artificial lung membrane, and the price is as high as 60000 yuan/ton to 70000 yuan/ton. Especially after the outbreak of the new crown, the global demand for artificial lung membrane necessary for the treatment of critically ill patients showed explosive growth, PMP prices soared to more than 100000 yuan/ton, and in short supply, the overall demand is strong.

As the raw materials for the production of PMP have been monopolized by foreign companies in technology and production, domestic PMP materials and their raw materials are in a technical gap, all rely on imports. With the surge in demand for PMP materials and their hollow fiber membranes at home and abroad, the Petrochemical Research Institute has carried out the research and development of PMP materials and their raw materials in 2020. Up to now, the key indicators of this project technology have reached the import level, in line with high-end medical equipment and medical protection needs.

In April 2023, on behalf of PetroChina, the Petrochemical Institute participated in the project of "Biomedical Materials Innovation Task Unveiling Leading the List" jointly organized by the Ministry of Industry and Information Technology and the State Food and Drug Administration. After competition, the PMP field project was successfully unveiled.

At present, the Petrochemical Institute has developed a 1,000-ton 4-MP-1 monomer and PMP material production technology package, and plans to build a 1000-ton/year demonstration device to realize the industrialization of 4-MP-1 monomer and PMP materials, solve the "stuck neck" problem in the whole process of raw materials and materials, promote the high-quality development of PMP and other new materials, and provide raw material guarantee for PetroChina's "cutting-edge" manufacturing in China's high-end medical and communication fields, it is of great significance to maintain the security and stability of the industrial chain supply chain and enhance the core competitiveness of domestic high-end new materials.
