Silica gel PORESPHERE™ A indicator OG
PORESPHERE™ A-Indicator OG is a high-purity, tightly porous silica gel specifically designed for the reliable adsorption of water vapor. Its finely tuned pore structure allows
Silica gel, also known as silica gel, is an amorphous, porous material. Chemically, it consists of silicon dioxide (SiO₂) and has a high specific surface area, typically 600–800 m²/g. Silica gel is available with or without a color indicator. The color indicator is a silica gel mixed with dye that changes color upon absorbing moisture, thus serving as a moisture indicator.
Silica gel is used as a desiccant in many industrial sectors, including filter technology, gas processing, electronics, transformers and the pharmaceutical industry.
PORESPHERE™ is a high-quality silica gel, available with or without an indicator. PORESPHERE™ silica gel has a high adsorption capacity and a clearly visible humidity indicator. Its adsorption capacity ranges from 35% to 90%. It can be used at temperatures up to 100°C and at relative humidity levels above 10%.
