Silica Gel is a type of desiccant made from silicon dioxide, capable of reducing humidity levels by adsorbing water vapour and moisture. The moisture absorber with its large internal surface area can bring the humidity down to 40% in an enclosed environment and absorb up to 40% of its weight. The desiccant performs best in high humidity and room temperature environments. Non-reactive and odourless, the desiccant is often used in the Electronics, Food and healthcare industry.
Silica gel supplied in different mesh sizes and colours, Non-Indicating, Blue-Indicating and Orange-Indicating to meet requirements of different applications and industrial needs. Commonly packed in a porous desiccant bag or silica gel packets such as Tyvek material to prevent clutter within the packaging.
Clear or white silica gel, the moisture absorber is both non-corrosive and non-reactive to chemicals, making it a food-safe moisture-absorbing agent commonly used in food packaging. It does not undergo any visual changes during the moisture absorption process. Monitoring the desiccant by weight is an indicator of its saturation. Another alternative of monitoring would be to use the desiccant together with a humidity indicator.
The blue-indicating moisture absorber is incorporated with cobalt chloride and changes colour from blue to pink when saturated with moisture. The colour change provides a visual indication for replacement. Commonly used in the electronic and transformer industry. Blue silica gel should not be used in direct contact with food or medical products.
The environmental Gel (Envirogel) appears orange or yellow and turns to green when the desiccants become saturated with moisture. It is a pollution-free non-toxic desiccant that meets requirements that require to be environmental. Confirming to EU standards, the desiccant has a high adsorption capacity that will remove moisture at temperatures up to 65°C(150° F)
Here in Stream Peak, we also provide other desiccant and moisture adsorbing solutions. Humidity Indicator Card can also be used to ensure dehydration measure works!
