Driven by technological innovation, the polymer microsphere market has broad prospects

​​​​Polymer microspheres refer to polymer particles with a spherical shape and a particle size ranging from tens of nanometers to hundreds of microns. The surface of polymer microspheres is composed of hydrophilic polymers and has the characteristics of good viscoelasticity, good water-absorbing swelling, high mobility, and good diffusibility. It is widely used in medical, coatings, inks, cosmetics, oil field development and other fields. According to different raw materials, polymer microspheres can be divided into chitosan microspheres, dextran microspheres, PMMA microspheres, PLGA microspheres, PLA microspheres, etc.

The preparation methods of polymer microspheres include suspension polymerization, emulsion polymerization, emulsifier-free emulsion polymerization, solvent evaporation method, etc. Emulsion polymerization is the mainstream preparation method for polymer microspheres. Its production process includes raw material emulsification, polymerization, separation, dehydration, drying, etc. This method has the advantages of high yield of finished products and the ability to control the particle size accuracy of microspheres, but it only Suitable for producing microspheres with a particle size within 1 micron. In recent years, Chinese enterprises and scientific research institutions have continued to increase investment in research and development. In the future, emerging methods such as emulsifier-free emulsion polymerization and solvent evaporation methods are expected to be widely used in the preparation process of polymer microspheres.

PMMA microspheres, also known as polymethyl methacrylate microspheres, are representative products of polymer microspheres. They have the characteristics of strong adsorption, strong surface reactivity, and large cohesion. They are in high demand in the fields of optical materials, coatings, films, etc. . At present, my country’s PMMA microsphere production technology has matured, and its output continues to grow. The development of the PMMA microsphere industry is accelerating, bringing broad market prospects for my country’s polymer microspheres.

According to the “2023-2028 China Polymer Microsphere Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , polymer microspheres are widely used in medical, coatings, inks, cosmetics, oil field development and other fields. In the medical field, polymer microspheres can be used for molecular diagnosis, drug preparation, biochemical analysis, etc.; in the field of oil field development, polymer microsphere control and flooding technology can improve the water injection development effect, improve water flooding conflicts, and improve reservoir water flooding for oil fields. main technology. With the increasingly strong downstream demand, the development space of my country’s polymer microsphere industry will further expand.

The main manufacturers of polymer microspheres in my country include Nanotechnology, Wanhua Chemical, Chutian Technology, Advanced Microsphere Nano New Materials, etc. NanoVis Technology focuses on the research and development and production of polymer microspheres. Currently, the company’s products are widely used in in vitro diagnostics, biomedicine, flat panel display and other fields.

Industry analysts said that polymer microspheres are rich in types and widely used in many fields. With the gradual release of market demand, the development prospects of the industry Keep improving. In recent years, Chinese enterprises and scientific research institutions have continued to increase their research and development efforts on polymer microspheres, and the application scope of polymer microspheres in my country will be further expanded in the future.
