Esschem Europe  offers a variety of ground glasses with a wide range of particle sizes. These glasses are ground to meet your filler requirements. We offer precise X-Ray opacity, a range of options for composition, and a refractive index for aesthetically pleasing composites.

Glass Fillers:

Esschem Europe Glass features optimized levels of silane and improved hydrophobicity,  properties  which  may  result in improved adhesion & compatibility of the organic / inorganic surfaces in the composite.  This results in improved mechanical strength of your composite. This  is  a barium borosilicate glass, BBAS, containing 33% barium oxide.
