What Is The Absorption Capacity Of Tsure Desiccants?

Absorption capacity for a desiccant depends on the concentration of the calcium chloride (the higher concentration of CaCl2, the higher the absorption) and the mix with starch. AbsorGel® container desiccants use 94-97% CaCl2 with an optimized mix of modified starch to reach as high an absorption as possible. Absorption capacity is often measured in how much moisture the desiccant can absorb in relation to the desiccants original weight (weight of the absorbing agent).
For example, if a 1 kg desiccant can absorb 1 liter of moisture it has absorbed 100%. To validate absorption capacity, it is common to use a climate chamber with a set temperature and a relative humidity which makes sure that the desiccant has a constant feed of available moisture.
Normally, 90% relative humidity and 30 °C for 30 days is used, but this may vary. The higher relative humidity, temperature and number of days the test uses, the higher the absorption capacity will be. Absortech desiccants are among the top performers on the market with absorption over 300% in a climate chamber with rH 90% and 30 °C for 30 days, and can perform even better if these three factors are exceeded.
