Molecular sieves
Molecular sieves from Nanjing Nalgene Industry & Commerce Company Limited are synthetic zeolite adsorbents formulated as sodium, calcium, or potassium aluminosilicates. The supplier offers industrial-grade material in types 3A, 4A, 5A, and 13X, with bead sizes ranging from 1 mm to 5 mm for gas drying, petrochemical refining, and refrigerant system applications. Each grade targets specific molecular adsorption, with 3A used for dehydrating liquids and gases, 4A for static dehydration in closed systems, 5A for separating normal and iso-paraffins, and 13X for removing larger polar molecules.
The material’s crystalline structure provides high adsorption capacity and thermal stability, critical for maintaining performance in moisture-sensitive environments. Standard for molecular sieves, the product exhibits a typical pore diameter of 3 Å for 3A, 4 Å for 4A, 5 Å for 5A, and 10 Å for 13X, with a standard bulk density of 0.65 - 0.75 g/ml. These sieves are chemically inert, resisting degradation in aggressive industrial conditions, and are commonly supplied in bulk drums or super sacks for large-scale operations.
Primary buyers include chemical processing plants, natural gas facilities, and HVAC manufacturers requiring precise moisture control to protect equipment and product integrity. The supplier’s location in Nanjing, Jiangsu, positions it for efficient export logistics via Chinese ports. Importers should confirm packaging options, as these sieves are typically shipped in moisture-proof containers to preserve adsorption capacity during transit. The material’s standard regeneration temperature ranges from 200 to 300 °C, depending on the grade and application.

Sourcing Molecular sieves from Nanjing Nalgene Industry & Commerce Company Limited - China Import Guide
Before ordering, verify the supplier’s ability to provide the required molecular sieve type and bead size, as Nanjing Nalgene Industry & Commerce Company Limited lists multiple grades but does not specify stock levels. Request a certificate of analysis (CoA) for the batch, confirming pore size distribution, adsorption capacity, and moisture content. For critical applications like LNG drying, ensure the material meets ASTM or equivalent standards for the intended grade.
Confirm logistics details, including packaging type (drums vs. super sacks), moisture-proofing measures, and port of loading in China. Standard lead times for bulk orders can range from 4 to 8 weeks, depending on production schedules, so clarify this upfront. Incoterms such as FOB Ningbo or CIF destination port are common; agree on these and payment terms (e.g., L/C or T/T) to avoid delays.
Quality checks should include testing a sample for adsorption capacity and particle size distribution. Use a sieve analysis for bead sizes and a gravimetric method for water adsorption. Request documentation such as MSDS, CoA, and compliance certificates (e.g., ISO 9001 if available). For high-value shipments, consider third-party inspection at the loading port to ensure the material meets the specified technical parameters.
