Hollow Ceramic Microspheres

Cerablak® HCMs are unique, black or white hollow microspheres (micro-balloons) that exhibit outstanding thermal stability. These ultra-low-density spheres can be produced in very small particle sizes (diameters from 5 to 100 microns), can withstand a broad pH range (2-9), and combine low thermal conductivity with high emissivity.  And no other micro-balloons can match the performance of Cerablak® HCM at high temperatures. These innovative spheres bring value to various market applications—from household paints to fire barrier coatings.
