Vitro Minerals VitroBloc™ 350 Recycled Glass Powder Antiblock
Categories: Ceramic; Glass

Material Notes: VitroBloc™ Glass Powders, VB-350 and VB-500, are high clarity, inorganic antiblock additives made from recycled glass. The feedstocks for VitroBloc™ are pure glass, which is free of crystalline silica or other impurities. VitroBloc™ products are white powders finer than 40 µm top size with a very low level of minus 5 µm fines. The products are designed for excellent blocking and clarity properties utilizing a recycled powder. VB-350 and VB-500 offer two different refractive indices and specific gravities to optimize film properties of clarity, haze, and weight.
