Certification Description:Specification.White Silica GelMaterial Description: Glass, har, irrgualr shaped granules with a very high purity of approx.99.5% SiO2 (Dry basis) and an internal surface area of approx.800 m2/g. Because of its very large surface area Silica gel exhibits a high adsorption for water vapour. Silica gel can be reactivated without significantly impairing the efficiency. It is therefore very economical, easy to dispose of and without any known adverse effects on the evironment. Supplied as desiccant absorbent, silica gel conforms to US MIL-D3716, BS-2540, DIN 55473.Formula: SiO2.
