The Microblast product line is the industry standard in blasting media, delivering high-quality components with superior aesthetics in a variety of applications including automotive, aerospace, electronics, home appliances, sporting goods and architecture. With their unique characteristics, Microblast ceramic beads also are used for precision blast cleaning applications to achieve the smoothest and most uniform surface finish on treated parts.


Engineered fine ceramic blasting
Microblast fine ceramic beads are produced through a unique proprietary process developed over many years by ZirPro engineers. Microblast ceramic blasting media are characterized by:
- Extremely tight particle size distributions
- Refined spheroidal bead shapes
- High mechanical strength
