Typical Application For insulated glass adsorption at the same time insulating glass of water and organic residues, so that the insulating glass, even in very low temperatures remained bright and clean and transparent, at the same time be able to reduce the insulating glass full season as a result of the temperature difference between day and night and are subject to great changes both within and outside the powerful Pressure on the poor, solve common insulating glass desiccant easy to make hollow glass or expansion and contraction caused by broken distort the issue, fully extend the life of insulating glass.

Very Selective Adsorption

Insulating glass molecular sieve has been designed as a high water capacity adsorbent with the lowest capacity for air or other gases. The highly selective pore structure of assures excellent water dew point protection while eliminating the co-adsorption of gases in the sealed air space.

Low Deflection

Because insulating glass molecular sieve minimizes pick up of other gases, it reduces adsorbent contribution unit deflection and stress under severe climatic conditions.

Economy and Performance

It increases gas-filled nit production rates since units can be sealed immediately after filling. In addition, the use of insulating glass molecular sieve maintains unit sound and heating insulation values by minimizing the adsorption of gases from the sealed space.

Homogeneous and Non-Separating

Unlike blends of two different desiccants that separate because of different component densities,insulating glass molecular sieve is homogeneous and uniform. Each bead is like every other. There’s no need to worry about unit-to-unit variation, which can occur with blends.

Residual Moisture

Insulating glass molecular sieve is supplied as a fully activated Insulating Glass Adsorbent, ready for use in spacer filling operations.
