About this product
Product information from the supplier.
Product Introduction
Featuring a lightweight spherical structure and smooth reflective surface, hollow glass microspheres are primarily composed of alkali-lime borosilicate glass. What sets them apart is the unique blend of properties: low density, robust strength, minimal thermal conductivity, superior electrical insulation, heat resistance, reliable chemical stability, and outstanding fluidity. Such advantages make them indispensable in diverse fields: adhesives, corrosion-resistant & insulating coatings, construction materials, rubber, synthetic wood, oilfield cements, and lightweight automotive composites.
Specification
Common sizes are 2-130 µmWe also accept customization if you need.
