Silica gel bulk has a range of possible applications: Industrial solutions Relative humidity buffer (RH buffer) Filtration systems Electronic equipment Making dried flowers Ozone filters Air dehumidifiers Etc. Silica Gel Bulk orange features a moisture indicator. When the moisture percentage exceeds 20% RH, the granules will turn from orange to green/blue. When the silica gel is saturated and has attained a green/blue colour, the granules can be heated (up to a maximum temperature of 80 °C; higher temperatures than that would destroy the silica gel granules) until they have turned orange once more. In this manner, the silica gel granules can be reused. The orange silica gel is environmentally friendly and harmless. The gel does not contain any heavy metals as indicator and is free of DMF (dimethyl fumarate).
