Polymer Microparticles Product List and Ranking from 4 Manufacturers, Suppliers and Companies

Magnetic polymer microparticles

The particle size of magnetic polymer microparticles ranges from 1.0 to 20 μm, and they are very uniform, with a CV of typically less than 3.0%.

Magnetic polymer microparticles have a layered structure, with a porous polymer core inside and a polymer of different materials on the outside. The magnetic material is filled in the gaps between the layered structures. The particle size ranges from 1.0 to 20 μm and is very uniform, with a CV usually less than 3.0%. They are applied in various scenarios. The surface of the microparticles has very low nonspecific adsorption, making them particularly suitable for the development of highly sensitive biological detection methods, such as the development of magnetic microparticle chemiluminescent reagents. They can also be used in various fields such as immunoprecipitation, co-precipitation, cell magnetic separation, and nucleic acid specificity capture, among others in biomagnetic separation.

[Technical Article] Case Studies on Solving Issues with Hollow Polymer Microparticles

Differentiating from competitors through the development of insulating film materials for semiconductors compatible with 5G! What are the customizable organic materials that achieve low dielectric properties?

5G, the next-generation mobile communication system, can transmit large volumes of data at high speeds. The development of low-dielectric semiconductors and substrates that suppress signal transmission loss in the high-frequency range is required. 【Key Issues】 We want to promote low-dielectric properties not only through resin modification but also with additives. We need additives that are compatible with the base resin and customizable. 【Solution Points】 Hollow polymer microparticles can impart low-dielectric properties due to the air layer inside the particles. They are lightweight and flexible, and customization of particle size, composition, and heat resistance is also possible. For more details, please check the link below.

These are monodisperse microparticles made from highly cross-linked polymers, available in a rich variety of specifications with fine size increments, and are widely used in fields such as LCD and PDLC. They are measured using certified measuring instruments (Beckman Coulter Counter Multisizer) and certified methods, and to ensure measurement accuracy, they are calibrated with traceable standard particles from NIST before each measurement. Since the ion content of microparticle products can directly affect the quality of liquid crystals, deionized water is used in the manufacturing and cleaning processes, and products are regularly sampled and inspected. The manufacturing process does not use substances prohibited by the European Union RoHS directive, and does not contain organic compounds or heavy metals banned by RoHS. Product characteristics: * The particle size is very uniform, with a coefficient of variation (CV) of less than 3.5%. * It has excellent monodispersity, with no overlap or aggregation. * It has high purity and contains no contaminants. * It has high mechanical strength. * It possesses excellent heat resistance, cold resistance, and chemical resistance.
