Poly-4-methyl-1-pentene (PMP) has high technical barriers and my country has not yet achieved domestic production.

Poly-4-methyl-1-pentene (PMP) is a new type of thermoplastic resin. It is mainly produced by the dimerization of propylene to obtain the monomer 4-methyl-1-pentene, which is then polymerized using a Ziegler-Natta catalyst or a metallocene catalyst. And get. PMP can be formed by injection molding, blow molding, extrusion and other methods. It has the advantages of high light transmittance, good heat resistance, non-toxicity, chemical corrosion resistance, creep resistance, and excellent electrical insulation.

With its excellent comprehensive performance, PMP can be used to prepare artificial kidney dialysis membranes, oxygenation membranes, hollow fiber membranes (PMP membranes), etc., and is widely used in the field of medical devices. In addition, PMP can also be made into microporous membrane materials, adsorption materials, and mold materials for packaging. It has huge application potential in fields such as high-frequency electronic components and 5G communication base stations.

Extracorporeal membrane oxygenation (ECMO), commonly known as artificial lung, is an important emergency medical equipment, mainly used in ICU. ECMO technology is relatively difficult, and global suppliers mainly include Germany’s McVision, the United States’ Medtronic, and the United Kingdom’s Renova. The oxygenation membrane is one of the core components of the ECMO system, responsible for the blood oxygenation function. In the past three years, due to the outbreak of the new coronavirus epidemic, the clinical application rate of ECMO has continued to rise. Against this background, the development of the oxygenation membrane market has accelerated, and the upstream raw material PMP Market demand has also grown.

According to the “2023-2027 China poly-4-methyl-1-pentene (PMP) industry market supply and demand status and development trend forecast report released by the Industrial Research Center” shows that PMP has special grain size and morphology, and the preparation process is difficult to control. Therefore, there are very few PMP production companies and limited production capacity globally. Japan’s Mitsui Chemicals is the main supplier. At present, Chinese enterprises mainly carry out related business around PMP modification and PMP products. PMP materials have not yet been industrialized and the demand still relies on imports. However, the procurement cost of imported PMP is high and difficult. In the context of intensified international conflicts, there are instability factors in the supply of PMP, which is not conducive to the long-term sustainable development of the industry.

In the context of the release of ECMO clinical application demand and the accelerated construction of 5G base stations, the PMP market has broad development space and there is an urgent need for domestic replacement. In 2021, biofilm medical materials, medical polymers, inorganic membrane materials, etc. will be selected in the key projects of “High-end Functions and Intelligent Materials” of the “14th Five-Year Plan” national key research and development plan. Under the guidance of national policies, major enterprises, scientific research institutions, and hospitals have increased their enthusiasm for research on PMP and PMP membranes. In the long term, as research continues to deepen, PMP is expected to gradually break through relevant technical bottlenecks and achieve localized production.

Industry analysts said that PMP has excellent comprehensive performance and broad application prospects. However, due to high production technical barriers, there are few PMP manufacturers in the world. , production capacity is limited, and my country’s market demand mainly relies on imports. PMP is one of the mainstream preparation materials for the oxygenation membrane, the core component of the ECMO system. Under the general trend of domestic substitution, more and more companies are deploying ECMO, which is bound to increase the demand for PMP applications, and the PMP industry has broad development space.
