Production Base

DCS automated process control

Tiangang applies DCS process control across production, with finished products and intermediates integrated on the same site to reduce batch-to-batch variation. What this means for customers is concrete: stable performance in large-volume supply, with no re-qualification every time the batch changes.

ISO 9001 quality system

Certified to GB/T 19001-2000 / ISO 9001:2000 on 16 January 2004, covering the full process from raw material and intermediates through to finished product, with batch traceability.

Technology through joint venture

A 50/50 joint venture with Clariant of Switzerland, one of the world's top 50 specialty chemical companies, brings international technology systems in while keeping local, fast-responding capability.

Local service in Europe

Tiangang Chemicals Europe B.V. in Belgium handles technical development and service as well as marketing. European customers have a technical contact locally instead of working across time zones.

Asia's first integrated 10,000-tonne finished product and intermediate base

Tiangang started up the first phase in 2011, with light stabilizer finished products and intermediates produced on the same site. Key intermediates no longer have to be bought in, so the quality variation and supply risk of external sourcing are handled inside the plant.

Capacity and expansion pace

The Cangzhou site has a combined annual capacity of 50,000 tonnes for light stabilizers and intermediates. In 2024 the joint venture received environmental approval for a 1,300 t/y light stabilizer expansion, leaving room to ramp up high-end grades.
