Insulating glass 3A molecular sieve is used to adsorb continuously an amount of moisture from the interspaces, maintains the proper dew point of the space between the inner and outer panes of insulating glass, minimize pressure changes which can eventually leads to distortion of insulating glass or even broken. The product can extend the lifetime of insulating glass unit with low dust, low attrition and low gas desorption to resulting in enhancing the quality, performance, and reliability of insulating glass.
1. Specially used for adsorption of the water vapor and organic residues in insulating glass to keep and stabilize dew point of insulating glass.
2. Don’t adsorb sulfur hexafluoride.
