Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Adsorbents And Desiccants. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This 3A molecular sieve desiccant is intended for use in the sealed cavity of insulating glass units (IGUs). It adsorbs residual moisture within the cavity to help limit internal condensation as temperatures change.
The material is described as the potassium form of a type A alkali-metal aluminosilicate crystal structure, with an effective pore opening of approxima adsorption of at least 20% by weight at 50% relative humidity and 25°C, bulk density of at least 0.72 g/ml, compressive strength of at least 20 N per piece, adsorption temperature rise of at least 30°C under a stated 20 ml/20 ml test, dust content of no more than 30 ppm, particle-size pass rate of 98%, and wear rate of no more than 0.2% by weight.
The listed ammonia adsorption capacity is no more than 0.2% by weight, although buyers should request the applicable test method and current batch documentation before relying on this value.
For IGU production, moisture adsorption is presented as supporting a drier sealed space and helping reduce the likelihood of condensation that can impair visibility. The source also describes selective adsorption of water while allowing other gases to pass.
Suitability for a particular spacer-filling system, sealant package, gas fill, climate exposure, or finished-glass specification is not established by the available information.
Before procurement, confirm the required bead-size tolerance, adsorption test method, initial moisture content, regeneration or handling requirements, storage life, packaging format, and lot-level inspection documentation.
Buyers should also verify compatibility with their spacer profile, filling equipment, primary and secondary sealants, and production conditions. Any required building-material compliance, safety documentation, or third-party certification should be requested and reviewed separa
