Product Description

Molecular Sieve 3A Ns-E for Insulating Glass, Size 05mm-0.9mm by Manual

CHICO Brand Adsorbent for insulating glass fully cover the current requirement of EN1279-4 and 6, it not only technical can meet the requirement of EN1279 but also it can save money for the end-users in the parameters of lower density , higher adsorption capacity and also it will safeguard your IG unit in the ideal way together with other insulating glass components-Primary sealant, Secondary sealant, and Spacer bar.

 Molecular sieve 3A
Most molecular sieves have been affinity to water, such as other molecular sieve 4A, 5A, 13X, type Y and so on. They all also adsorb other molecules from air. The pore of  molecular sieve 3A is 3 angstrom, which can only adsorbs molecule smaller than this size, water molecule is just meet this size, so molecular sieve 3A can only adsorb water other than Nitrogen and Oxygen in air.
The following form lists 4 types of common desiccants often used in IG and their aperture values. This form also shows which kinds of molecules are likely to be absorbed by these desiccants.
 

Desiccant Type	Pore Size (angstrom)	Absorb Substances	Repel substances
3A	3	H2O	All others
4A	4	H2O, nitrogen	Ar, Kr, large molecule gases
13X	8.5	H2O, most gases, small molecule liquids	Large molecule liquids
Silica gel	200-300	All	Non

 
 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.
