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

This 3A molecular sieve is a potassium-form type A alkali metal aluminosilicate used as a physical desiccant. It has a nominal pore diameter of 3 angstroms (approxima ic water adsorption is at least 21%, and supplied forms include spheres and pellets.

Supported applications include drying ethylene, propylene, butadiene and cracked gas;natural-gas drying where reduced hydrocarbon co-adsorption or COS minimization is required;drying methanol, ethanol and other liquid alcohols;drying CNG;and static dehydration of air-filled or gas-filled insulating glass units.

Buyers should validate the grade against their actual feed composition and operating conditions before specifying it for a process. Available dimensional listings include spherical material in 1.7–2.5 mm and 3.0–5.0 mm ranges, plus pellet diameters of 1.6 mm and 3.2 mm.

Reported bulk-density, crushing-strength and size-ratio values vary by form and size. Packaging options listed for the product include carton boxes, carton drums and steel drums.

Before ordering, confirm the required particle form and size, adsorption test method, acceptable wear ratio, crushing-strength requirement, delivered moisture limit, regeneration procedure, packaging configuration and batch documentation.

For safety- or process-critical service, buyers should also request a current specification sheet and representative sample, then conduct qualification testing under the intended temperature, pressure, flow rate and gas or liquid composition.

Buyer tips

  • State quantity range and split-delivery needs before price comparison.
  • Add certification, material or inspection standards when they affect acceptance.
  • For time-sensitive projects, include target arrival date and destination.
  • For special applications, describe operating condition, installation environment and duty cycle.

FAQ

What should buyers confirm first?

Confirm application, specification, quantity, destination and lead-time requirements before comparing offers.

Can buyers inquire when specs are incomplete?

Yes. Add model, material, size, use case and inspection needs in the RFQ to make replies comparable.

How should this listing be evaluated?

Check title, category, specifications and related keywords against the actual sourcing requirement.
