ONYX ELITE 255 is a high purity alumina trihydrate used in the manufacture of solid surface materials. It yields low viscosities, excellent air release, reduced matrix settling and a very homogenous casting. ONYX ELITE 255 has a broad particle distribution with a controlled top size (-5% on 100 mesh) which yields excellent packing characteristics. The median particle diameter, controlled particle distribution and low contaminant level of ONYX ELITE 255 aid manufacturers in obtaining good cure, good translucency and excellent color, when compared to other products offered for solid surface applications. ONYX ELITE 255 is suitable for applications requiring high purity fillers to improve physical performance and yield consistent results.
