The global metallic microspheres market is anticipated to observe steady growth over the coming years. Microspheres are solid spherical particles available in sizes ranging from one to 1000 µm. Microspheres are classified based on raw materials used such as glass, ceramic, fly ash, polymer, metallic, and others. Metallic microspheres consist of glass and ceramic as ingredients and are used in automotive materials, aerospace and defense materials, biotechnology, construction, coating additives, cosmetics, and oil and gas consumables. The structural categorization of microspheres includes hollow or solid. The major application of the metallic microsphere is to provide EMI (electromagnetic interference) shield to circuits and devices. Silver coated microspheres are electrical conductors providing advantages of metal coating coupled with core microspheres. A typical example includes hollow glass microspheres offering low-density filler and conductive particle properties when coated with silver. Another application includes retro-reflective microspheres used on billboards and hoardings that are illuminated by headlights. Retro-reflective microspheres are solid barium titanate glass microspheres coated with half-shell aluminum. The sphere is coated in a hemispherical area with a thin aluminum shell, which produces bright retro-reflective responses directed back to the light source. Metallic microspheres are made from molten metal which is poured in an orifice which is passed through an electric field resulting in the formation of uniform metallic balls. Numerous other variations to the existing method have been done but the basic principle remains the same.
Increasing demand from existing and other upcoming application areas is expected to boost the metallic microspheres market demand for metallic microspheres over the forecast period. Metallic microspheres possess superior structural properties coupled with reusability and recyclability properties which is further expected to drive market demand. Increasing demand for efficiency as a result of rapid infrastructural development coupled with modernization will fuel the growth of the metallic microsphere market. However, metallic microspheres consist of metals, which have a restricted supply resulting in a high degree of price fluctuation is expected to be a potential restraint for the market. Additionally, higher costs incurred during research and development will also pose a challenge to the existing industry participants.
Key companies in the metallic microspheres market include TRELLEBORG AB, Sunjin Chemical Co. Ltd., Sinosteel Maanshan Institute of Mining Research Company Limited, Sigmund Lindner GmbH, Polysciences Inc., Phosphorex Incorporated, Momentive Performance Materials Inc., Mo-Sci Corp., Merit Medical Systems, Inc., Induchem Holding Ag, EKO Export SA, Dennert Poraver Gmbh, Cospheric LLC, AkzoNobel N.V., and 3M Company.
