Quality Assurance

As one of China’s leading light stabilizer manufacturers, Tiangang believes that “Quality First” is not merely a slogan, but a commitment every company and every employee makes to customers. For additives like light stabilizers that are used in tiny amounts yet are critical to product protection, stable and reliable quality directly affects the market performance of our customers’ products.

To this end, Tiangang has continuously invested in quality systems, inspection and testing methods and instruments since its founding. In line with ISO9001 standards, we have established a full-process quality assurance system covering raw materials, intermediates and finished products, equipped with HPLC, GC, UV spectrophotometry, thermal analysis and other testing equipment, achieving traceable and verifiable key indicators for every batch and ensuring the reliable quality of each and every batch.

In addition, Tiangang’s Application Technology Center provides in-depth technical services such as weathering performance evaluation and formulation optimization, safeguarding quality throughout the entire journey from product to application.
