![]() ![]() In the United States, silica gel is commonly used in food and pharmaceutical applications as only silica gel has been approved by the FDA for direct contact with these items. White silica gel is less expensive than indicating types and may be mixed with either blue or orange types to achieve humidity indication. The Silica is reusable and can be reactivated and reused by placing the beads on a non-food use oven tray and baking them between 100 degrees C and 120 degrees. Silica gel performs best at room temperatures (70° to 90☏) and high humidity (60 to 90 RH) and will drop the relative humidity in a container down to around 40 RH. White non-indicating silica gel beads contain no color indicator Typical applications include humidity control in packages and containers and moisture control in safes, closets, and other spaces. These beads turn light green when saturated. Orange indicating beads are best for applications where color change is desired and the material may be exposed to food or medicine. Blue indicating silica gel should be avoid in food, pharmaceutical, and other applications where human ingestion may occur. Silica gel comes in the form of glass beads. The color indicator is cobalt chloride, a carcinogen. Silica gel is one of most commonly used desiccant (sorbents) and consists of nano-porous Silicon Dioxide (SiO2). White Silica gel beads, Blue Silica gel beads and Orange Silica beads. This type is commonly used in compressed air and gas drying applications, as well as for tank breathers. Silica Gel Beads - Indicating & Non Indicating Type Silica gel beads also known as Round or Spherical Silica gel which is available in three different varieties. Several types of silica gel are available.īlue indicating beads are deep cobalt blue when dry and turn pink when saturated. safes, closets), to tank breathers for hydraulic oil in power transformer applications, to compressed air and gas drying. Tyvek dessicant packets, premium indicating silica gel beads, desiccant tin canister, environmental protection natural clay desiccant, molecular sieve. Orange to dark green (when saturated) Silica Gel beads have a more obvious colour change than previously available for improved application in the display. Silica Gel Beads contain methyl violet dye that. Silica gel (Beads) orange Material 99 amorph Siliciumdioxid (SIO2) Particle size 3 - 5 mm Storage at room temperature Reclaimable at 120 C Bulk. Its affinity for water makes it useful as a desiccant (drying agent) in a wide range of applications, from humidity control in product packaging and confined spaces (e.g. Therefore, desiccant silica gel packets are put in store-bought products to prevent damage due to humidity. Silica gel is a hard glass-like spherical bead of porous silicone dioxide.
