4a molecular sieve
The 4A molecular sieve from Pingxiang Xintao Chemical Packing Co., Ltd is a synthetic sodium zeolite A (Na12Al12Si12O48) with a precise 4-angstrom pore size. This structure selectively adsorbs water molecules while excluding larger compounds, making it highly effective for dehydration processes in gases, liquids, and refrigerants. The material is supplied in bulk bags or drums, suitable for industrial-scale applications where moisture removal is critical to product integrity or process efficiency.
As a type A zeolite, this molecular sieve typically exhibits a high adsorption capacity for water, with a standard moisture retention of around 22-25% by weight at saturation under typical conditions. It is chemically inert and thermally stable, with a standard regeneration temperature range of 200-300°C, allowing for repeated use in cyclic processes. The uniform pore structure also ensures consistent performance in applications like air separation, petrochemical refining, and solvent purification, where purity and reliability are paramount.
Industrial buyers in petrochemical, natural gas processing, and refrigeration sectors rely on this sieve for drying feedstocks, removing trace water from hydrocarbons, and maintaining system efficiency. Trade terms for bulk supply are negotiable, with packaging options including 25 kg bags or 150 kg drums. Buyers should confirm MOQ, lead times, and incoterms directly with the supplier, as these are tailored to order volume and destination. The product is particularly suited to markets requiring cost-effective, high-capacity desiccants for large-scale operations.

Sourcing 4A molecular sieve from Pingxiang Xintao Chemical Packing Co., Ltd - China Import Guide
Before placing an order, verify the exact particle size distribution and moisture adsorption capacity for your application, as these directly impact performance in dehydration systems. Request a certificate of analysis (COA) from Pingxiang Xintao Chemical Packing Co., Ltd to confirm compliance with your process requirements, including any industry-specific standards such as ASTM or ISO for molecular sieves.
Confirm logistics details such as packaging type (bags or drums), incoterms (FOB, CIF, or CFR), and lead times, which may vary based on order volume and destination port. For bulk shipments, discuss container loading plans and any special handling requirements, as molecular sieves are sensitive to moisture exposure during transit. Payment terms should also be clarified, with options typically including T/T or L/C for international orders.
Quality checks should include testing a representative sample for adsorption capacity, particle size consistency, and bulk density to ensure it matches the supplier’s specifications. Inspection during loading can prevent contamination or moisture ingress. Request documentation such as material safety data sheets (MSDS) and COAs, and confirm that the product is packed in moisture-barrier materials to maintain its adsorption properties during shipping.
