1. Molecular sieve

Molecular sieve (also called as synthesized zeolite) is a kind of silica-aluminates with micro-porous crystal. It is a frame-work which is constructed by SiO2 and Al2O3. Molecular sieve has very similar aperture value (only several A) and large surface area. There are relevant positive ions in its lattice to balance the negative ions in the crystal frame. Different molecular sieves have different shapes and different aperture values. We could separate different kinds of molecular by selectively using different molecular sieves. Water is a sort of polar molecule, molecular sieve type A has dramatic affinity for water. For the above reasons, molecular sieve is considered as the most ideal desiccant. The molecular sieve here mentioned is type 3A which is only for adsorbing water. The water adoption depth of molecular sieve 3A is above several dozen times higher than other any other applicable desiccants.

2. 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.

3. 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.

About us

Company details

SHANDONG NATERGY ENERGY TECHNOLOGY CO., LTD. was founded in 2003. Today Natergy is the largest molecular sieve 3A manufacturer for insulating glass in China. Natergy persists the principle of quality and makes commitment that Natergy molecular sieve 3A excludes calcium oxide, calcium chloride, molecular sieve 4A and other corrosive substances, thus it can prolong the lifespan of insulating glass up to 30 years long.

Natergy is an integrated company, it has its own production department, product re research department, equipment research department and associated lab, owns more than 20 patents. With self-developed automatic production line and monitoring center, Natergy is equipped with annual output capacity of more than 30,000 ton. With the certification according to EN 1279 by IFT, REACH registration of 1000+ MT and the approval of certified supplier by IGCC/IGMA., Natergy covers more than 20% market share in the world. Most importantly, Natergy is the unique company in the world which not only sells products, but also provides test kits to help the clients distinguish or judge the quality of molecular sieve 3A, thus keep the IG unit away from threat of corrosive desiccant.
