Glass microspheres
Moderate hardness, excellent blasting effect, resistant to breakage; widely used for metal surface treatment.
Product Overview
Glass microspheres are spherical particles manufactured from high-quality glass raw materials through processes such as high-temperature melting, atomization, and grading. The products feature high sphericity, moderate hardness, and resistance to fragmentation.
Widely used in metal surface treatment, rust removal, and polishing to significantly improve surface finish and adhesion. Compared to traditional sandblasting media, glass beads offer lower wear rates and can be reused, making them more cost-effective and environmentally friendly.
