Introduction
Molecular Sieve 3A is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; and this maximises lifetime when dehydrating such molecules.
• Preventing Internal Condensation: The Molecular Sieve Desiccant in insulating glass is used to adsorb moisture within the sealed space, effectively preventing internal condensation during temperature variations and improving visual clarity.
• Enhancing Thermal Insulation: The use of Molecular Sieve Desiccant helps reduce moisture content in the insulating glass, decreasing the gas conduction coefficient and thereby improving the thermal insulation performance.
• Extending Product Lifespan: Adsorbing moisture with Molecular Sieve Desiccant slows down the oxidation of metal spacers within insulating glass, leading to an extended lifespan, especially in harsh environmental conditions.
• Molecular Sieve Desiccant in insulating glass contributes to maintaining stability within the air space, enhancing sound insulation properties and reducing the transmission of external noise.



Features
High Adsorption Capacity: Molecular Sieve Desiccant exhibits a high adsorption capacity for moisture, effectively capturing and retaining water molecules within the insulating glass unit.
Selective Adsorption: It has a selective adsorption property, preferentially adsorbing water molecules while allowing other gases to pass through, contributing to enhanced moisture removal.
Thermal Stability: Molecular Sieve Desiccant maintains stability at various temperatures, ensuring reliable performance in both hot and cold climates.
Chemical Inertness: It is chemically inert, preventing any reactions with components of the insulating glass and ensuring long-term stability and effectiveness.
Non-Toxic and Safe: Molecular Sieve Desiccant is non-toxic and safe for use in insulating glass, meeting safety standards and regulations for building materials.
