About ALCellu

ALCellu Chemical Co., Ltd. has manufactured cellulose ethers and construction additives in Shijiazhuang, Hebei since 2012. One plant, 13 product lines — from HPMC and HEMC through RDP and calcium formate to starch ether, PVA and defoamer — supplying dry-mix mortar producers in 30+ countries.

2012: manufacturing cellulose ether since
80,000: m² plant area, Shijiazhuang
60,000: t/yr combined capacity
30+: export countries
≥99.5%: batch pass rate

Capacity

How the 60,000 t/yr is allocated

Capacity is not spread evenly across the product lines. If your order sits in one of them, this is the depth behind it — worth knowing before you plan a supply switch, not only a first order.

Confirmed annual capacity per product line.
Product line	Annual capacity (t/yr)
HPMC	17,000
RDP	11,000
HEMC	5,500
MHEC	5,500
Calcium Formate	5,500
HEC	4,000
PCE	3,500
PP Fiber	2,000
Starch Ether	1,500
PVA	1,500
Gypsum Retarder	1,000
Hydrophobic Powder	1,000
Defoamer	1,000
Total, all product lines	60,000

Manufacturing

Inside the plant

Export

30+ export countries

Material from the Shijiazhuang plant ships to 30+ countries. The main regions:

Africa
Middle East
Central Asia
South America
Southeast Asia
Russia & CIS

Your market does not have to be on this list — the export documents and the packing options are the same everywhere we ship.

Quality control

Where the batch numbers come from

The laboratory where samples are measured, and the raw-material store the material is drawn from.

A technician in a blue uniform lowering the spindle of a rotational viscometer into a beaker of clear liquid, with glassware and a balance on the bench. — A sample measured on a rotational viscometer in the plant laboratory.

A forklift moving stacked white bales inside a warehouse, with more bales stacked behind. — Refined cotton bales in the raw-material store, moved by forklift.

Quality

What the batch numbers mean

Two figures answer most of the consistency questions procurement asks. The viscosity one is quoted together with the condition it was measured under — without the condition the number means nothing.

Batch pass rate

≥99.5% of production batches pass release testing and ship. A batch that fails a release check is held — it does not leave the plant.

Batch-to-batch viscosity tolerance

−10% / +20% of the nominal viscosity. A grade with a nominal 100,000 mPa·s measures between 90,000 and 120,000 mPa·s from batch to batch: the spread comes from the test method, the test conditions and the instrument. That is why the TDS and the batch COA state the measurement condition next to the value — a number without its condition is not comparable.
