General Information
Molecular sieve is a high-performance desiccant specifically designed for the production of hermetically sealed and thermally insulated glass units (IGUs).

Its exceptional moisture absorption capacity helps ensure the long service life and reliability of insulating glass units by maintaining a dry internal environment.

The use of molecular sieve provides the advantage of minimal air absorption and desorption, virtually eliminating pressure variations that can cause deformation or mechanical stress within the window structure.

Key Benefits
Excellent moisture absorption capacity
Extends the service life of insulating glass units
Minimal air absorption and desorption
Prevents deformation and mechanical stress in window systems
Low bulk density
Suitable for air-filled and gas-filled insulating glass units
Does not absorb inert gases such as argon or krypton due to its optimized pore size
Maintains a low dew point over an extended period
Reduces the risk of condensation and glass failure

Applications
Molecular sieve is an essential component in the manufacture of insulating glass units, where it is placed inside the spacer bar to absorb residual moisture and maintain optimal conditions within the sealed cavity. It is particularly recommended for high-performance IGUs filled with air, argon, or krypton gas, helping to ensure long-term thermal efficiency and condensation-free performance.
