About Us — Molecular Sieve Manufacturer & Exporter
One company: R&D, production and sales
We develop, manufacture and sell our own molecular sieve at our plant in Zhengzhou, Henan — 6,000 tonnes a year — and supply industrial buyers and distributors in bulk: gas processors, air separation and PSA oxygen plant builders, insulating glass manufacturers, refrigerant and solvent producers, and chemical distributors.

What we do
R&D
Grade development and specification work done in-house, so a new duty can be matched to a product rather than to a catalogue.
Manufacturing
Hydrothermal synthesis, ion exchange, forming, calcination and screening of zeolite types A and X, plus carbon molecular sieve production.
Quality control
Adsorption capacity, crushing strength, attrition, size distribution, bulk density and loss on ignition tested on every released lot.
Export
Moisture-barrier packing, palletising, container loading and shipping documents for sea and air freight.

Documents we provide
Certificate of analysis
Measured values of the shipped lot, not a catalogue average.
TDS and SDS
Typical specification per grade, and a safety data sheet in the format required by the destination market.
Shipping documents
Packing list, commercial invoice and certificate of origin with every shipment.
REACH statement
Issued on request. Tell us the tonnage band you import and we will issue it for your compliance file.
Who we sell to
Industrial buyers and distributors only
Minimum order is 1,000 kg per grade. We do not sell consumer retail quantities and we do not sell to private individuals — molecular sieve performance depends on correct bed design, regeneration and handling, so it is supplied with technical support rather than over the counter.
Working with us
- Enquiry — you send the application, grade (or stream data), quantity, packing and destination.
- Recommendation — we confirm or propose the grade, and quote net price, packing, lead time and Incoterms.
- Sample — for new applications, a 1 kg sample ships against courier cost, with its COA.
- Order — production is scheduled, tested and released with a lot-specific COA.
- Repeat — your production record is kept, so reorders match the previous lot.
Our plant in Henan
We manufacture, test and pack at one site in Zhengzhou High-Tech Industrial Development Zone, Henan Province.
