Adsorbents & alumina, engineered for your process.
We manufacture activated alumina, molecular sieves and catalyst carriers on our own production lines, and source alumina and aluminum hydroxide directly from major producers. Clear specifications, honest supply routes, one engineer to talk to.
Five product families, each with its own page
Full specifications, applications and packing on every product page — so you can evaluate before you ever write to us. When you're ready, one email starts the conversation.

Molecular Sieves
3A, 4A, 5A and 13X zeolite sieves for air separation, ethanol dehydration, insulating glass and gas treatment.
View Product →
Activated Alumina
High-surface-area desiccant balls for compressed air, gas drying and water treatment — plus catalyst support grades.
View Product →
Catalyst Carriers
Activated alumina carrier spheres and pseudo-boehmite, matched to your catalyst system — evaluated by sample first.
View Product →
Alumina Powder
Calcined and alpha alumina for ceramics, refractories, coatings and polishing — bought directly from major producers in Zibo.
View Product →
Aluminum Hydroxide (ATH)
ATH flame-retardant and filler grades for cable compounds, solid surface and filled polymer systems — producer-direct.
View Product →Start from your application
Most buyers arrive with a process, not a product name. Find yours — we'll point you to the right media.
Air Separation
Front-end purification decides ASU reliability. Activated alumina takes bulk water; 13X molecular sieve removes water and CO₂ before the cold box.
Ethanol Dehydration
Vapour-phase dehydration on 3A molecular sieve takes hydrous ethanol to fuel grade — selectively adsorbing water, not ethanol.
Insulating Glass
Low-dust 3A desiccant in the spacer frame keeps sealed units dry and fog-free for their service life.
Gas & Air Drying
Compressed air, natural gas and LPG dried to specification dew points with activated alumina or molecular sieve, selected by duty.
Refining & Catalysis
Carrier spheres and pseudo-boehmite matched to the catalyst system — pore structure, strength and purity confirmed by sample evaluation.
Ceramics & Compounds
Calcined and alpha alumina for ceramics and refractories; ATH for halogen-free flame-retardant cable and polymer compounds.
A supplier that answers like an engineer
Honest supply routes
What we manufacture is labelled "Own Production". What we source is labelled "Direct Sourcing". No inflated story — you always know where your material comes from.
Evidence before orders
Datasheets, sample COAs and test samples are available before you commit. Judge the media in your own process, not from a brochure.
Clear EXW pricing
One clear ex-works price. Ocean freight changes daily, so it is calculated honestly for your order and destination — never bundled invisibly into the product price.
One direct contact
Your inquiry goes to Barry Wang, engineer — the person who will also handle your order. No call centre, no hand-offs, no repeating your specifications.
Media is a small line in your budget — until the bed fails.
Change-outs are planned around your shutdown window, not our convenience. Tell us the vessel and the date; we work backwards from there.
Plan a Change-OutMade on our lines. Checked batch by batch.
Activated alumina, molecular sieves and catalyst carriers are produced in Zibo, where alumina chemistry is the local industry. Every shipment is accompanied by its batch certificate of analysis.
- Grade selection confirmed against your operating duty
- Batch COA supplied with every shipment
- Test samples available before commitment
- Packing formats confirmed per order — bags, drums, bulk bags

From first email to shipment, in four steps
Send an inquiry
Email us your application, current media and quantity. Two minutes is enough to start.
Confirm the grade
We reply with the matching grade, full datasheet and a clear EXW quotation.
Test a sample
Evaluate a sample in your own process before committing to a full order.
Order & shipment
Batch COA with the goods, packing as agreed, freight arranged per your order.
Ask for the dossier, not the slogan
Everything a technical buyer needs to evaluate us is available before an order — just ask by email.
Full Datasheet
Grade, form, particle size and typical measured properties for the exact product you're evaluating.
Sample COA
See the batch certificate format before you order, so your QC knows exactly what will arrive.
Test Sample
Run the media in your own process, against your current material, before committing.
Packing Spec
Bag, drum or bulk-bag formats, weights and palletisation — confirmed in writing per order.
The purification package: guard layer + 13X
Most ASU front-end beds we supply are a package: activated alumina below for bulk water, 13X molecular sieve above for water and CO₂. Send us the vessel drawing or dimensions and we'll work out the split, sizes and quantities with you.

When to change out air-separation purification media
Bed life is not a calendar date. The signals that a purification bed is nearing its end — and the data to prepare before ordering its replacement.
