Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Molecular Sieves. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
Product overview This 4A molecular sieve is the sodium form of a Type A alkali aluminosilicate crystal structure. Its nominal pore diameter is 4 angstroms (0.4 nm).
The material is described as adsorbing molecules with kinetic diameters below approxima rs of 1.7–2.5 mm or 3.0–5.0 mm and pellets with listed diameters of 1.6 mm or 3.2 mm. The product is light grey.
The specification table lists static water adsorption of at least 22%, static methanol adsorption of at least 15%, water content of no more than 1.0%, and wear ratio of no more than 0.20% across the listed configurations. Listed physical properties vary by form and size.
Spheres have a minimum size ratio of 98%, with bulk density of at least 0.72 g/ml for 1.7–2.5 mm material and at least 0.70 g/ml for 3.0–5.0 mm material. Their listed crushing strengths are at least 35 N per piece and 85 N per piece, respectively.
Both pellet sizes have a minimum size ratio of 96% and bulk density of at least 0.66 g/ml. Listed crushing strength is at least 35 N per piece for 1.6 mm pellets and at least 70 N per piece for 3.2 mm pellets.
Listed applications include drying and carbon-dioxide removal from natural gas, LPG, air, inert gases, and atmospheric gases;removing hydrocarbons, ammonia, and methanol from gas streams;use in air-brake units for buses, trucks, and locomotives;packaging desiccant applications;and removing water from ethanol.
Application suitability depends on the feed composition and operating conditions.
Buyer confirmation points Before ordering, confirm the required particle shape and diameter, the specification that will govern water content because another product attribute states 1.5% maximum while the detailed table states 1.0% maximum, and whether the quoted adsorption and crushing-strength values apply to the selected grade.
Buyers should also confirm operating temperature, pressure, humidity or water loading, target outlet specification, regeneration method, cycle conditions, contaminant profile, required test method, packaging format, lot documentation, and whether a sample or pilot test is needed.
Listed packaging options include carton boxes, carton drums, steel drums, plastic drums, and metal drums, but the available format and net weight should be verified for each order.
