Molecular sieve 3A and insulating glass desiccant
If use other molecular sieve as desiccant, these molecular sieves can also adsorb nitrogen or oxygen in air at lower temperature, and could release air at higher temperature, the inflated and shrinking air could cause window to be distorted with the temperature changing at day-night or seasons changing. Up to now, molecular sieve 3A is the unique proper desiccant which is suitable for insulating glass unit.
CHICO sieve (insulating glass desiccant)
3A insulating glass (IG) desiccant (CHICO sieve) is made from molecular sieve 3A. This IG desiccant can deeply co-adsorb resident moisture and organics in insulating glass, keep the IG clear and transparent even at very low outside temperature, prevent the condense of inside vapor. More importantly, it can resolve the problem of window distortion caused by IG inflation and shrinking under season or day-night temperature changing; this would prolong the life span of IG windows considerably.

140kg fiber drum
All sizes of big bags
We could also design different kinds of packages according to requirements of customers
Precautions
1. The insulating glass desiccant should be sealed and stored before use. When in use, it should be filled quickly, and the unused molecular sieve should be sealed in time to avoid moisture absorption.
2. Molecular sieve that cannot be determined whether it absorbs moisture should be tested for temperature rise. When the temperature rise is lower than 33 degrees Celsius (25 grams molecular sieve/25 ml water), it cannot be used again and should be recycled by the manufacturer.
3. The manufacturer should have at least two detection methods for temperature rise and molecular sieve desiccant outgassing.
