Irradiation modification can improve material properties and there is huge room for industry development

Radiation modification refers to the use of ionizing radiation to improve the physical and chemical properties of polymer materials, thereby increasing the application value of the material and broadening its application scope. Radiation modification generally uses gamma rays and electron beams as radiation energy. After being irradiated by gamma rays or electron beams, polymer materials undergo cross-linking, grafting, compounding, polymerization, cracking, degradation and other reactions, thereby changing the material properties.

Methods for modifying polymer materials include thermal processing, chemical processing, light processing, etc. In contrast, radiation modification does not need to be carried out at high temperatures, and there is no need to add catalysts, photoinitiators and other additives, and conventional material modification can be obtained. High-performance materials that cannot be obtained by sexual methods. Radiation modification can prepare heat shrinkable materials, wire and cable materials, battery separator materials, PTC thermistor materials, super absorbent resins, rubber, coatings and inks, ultrafine powders, etc., which are widely used in electronics, electricity, home appliances, instrumentation, In industrial equipment, automobile, shipbuilding, petrochemical and other industries.

Radiation modification can improve the performance of materials. For example, after radiation modification of polyolefin, its melting point, mechanical strength, and oil resistance are increased; after radiation modification of low-density polyethylene, its melting point is greatly increased. , and the elasticity, impact resistance, corrosion resistance, dielectric properties, etc. are improved; after irradiation modification, polytetrafluoroethylene can be cracked into ultra-fine powder with a diameter of micron level, and the friction coefficient is extremely low. Therefore, there is a large market space for radiation modification.

According to the “China’s Irradiation Modification Market Feasibility Research Report 2022-2026” released by the Industrial Research Center, if it can be obtained If fully developed, the output value of my country’s radiation modification industry is expected to reach about 30 billion yuan. Under this circumstance, if the output value of radiation modification and downstream industries is calculated at the same time, it is expected to reach about 160 billion yuan. It can be seen that my country’s radiation modification industry has huge development potential, so the number of domestic companies entering the industry is constantly increasing.

my country’s radiation modification technology has undergone continuous development, and its industrial development is relatively mature at this stage, with a large market space in the future. The main enterprises related to radiation modification in my country include China General Nuclear Technology, China Tongren, CICC Radiation, etc. Irradiation equipment has high technical content, requires professionals to operate, needs to be equipped with professional workshops, and has high protection requirements. In addition, the state has strict approval and supervision of irradiation factories. Therefore, the entry barriers to the radiation modification industry are high, including high investment thresholds and High qualification threshold makes it difficult for companies with insufficient strength to enter the layout.

Industry analysts said that radiation modification is an aspect of the application of radiation technology and can produce products that cannot be achieved with traditional modification technology. The resulting new, high-performance materials. Against the background of the continuous upgrading of my country’s industrial technology, the demand for high-performance materials in the Chinese market continues to grow. Radiation modification plays an important role in promoting the product upgrade of my country’s materials industry and has huge room for development. However, the irradiation industry has high investment and high qualification thresholds, making it difficult for weaker companies to enter the market.
