![]() These are conditions where moisture damages such as mould, bad smell, peeled labels and collapsed packaging are more likely. Our first conclusion is that calcium chloride performs better than silica gel in tougher conditions, especially when the relative humidity is high. If that happens, their capacity to remove moisture remains low and very constant. #SILICA GEL DESICCANT FULL#Due to the physical characteristics of the adsorption process, silica gel desiccants may be full up quickly.Calcium chloride increases its capacity to absorb water over time because the absorption process makes the moisture dissolve into the calcium chloride.Calcium Chloride has a much better performance when the relative humidity is high.At high temperatures, it might actually release moisture into the air. Silica gel works well at unexceptional temperatures, while it may lose the capacity to adsorb at higher temperatures.The different processes affect how they perform in different environments: Absorption means that the water molecules dissolve into the calcium chloride rather than cling to the surface of it, as it does to silica gel. Hygroscopic materials can reach a balance with the surrounding environment and absorb moisture when the relative humidity is higher than the EMC, which stands for Equilibrium Moisture Content ( we talked about it in this insight). The silica gel is a very porous component with a high number of voids that may contain water when needed.Ĭalcium chloride, on the other hand, is hygroscopic and deliquescent which means that it absorbs moisture and turns into liquid. Silica gel does it by adsorption, which means that the water molecules adhere to the surface of the silica gel. Silica gel and calcium chloride have different ways to remove moisture from the surrounding environment. How silica gel desiccants remove moisture from the air In this insight, we’ve done just that for you, and by investing a couple of minutes, you’ll get a grip of how your company (and the environment too) can benefit from a switch from silica gel to calcium chloride desiccants to keep your goods safe and dry. The popularity of silica gel desiccants has led to few people stopping to analyze if there aren’t superior alternatives for protecting their company’s products. Bags filled with a few grams of silica gel are used for moisture protection in everything from shoe boxes to packaging for electronics. ![]()
