About Kemai Chemical Co., Ltd.
Kemai Chemical Co., Ltd. is a Chinese rubber chemicals manufacturer founded in 2002 and headquartered in the Gulin Industrial Zone of Dagang, in Tianjin's Binhai New Area. From that base and its production plants in several provinces it has grown into one of China's largest makers of rubber additives, with the TMQ antioxidant as its flagship product, for which it claims world-leading status with annual capacity of around 50,000 tons.
Its catalogue is organised as complete systems for rubber compounding: a vulcanisation system built around accelerators such as MBT, MBTS, CBS and DPG; an anti-ageing system centred on TMQ and other antioxidants protecting against oxygen, ozone, heat and fatigue; processing aids that improve flow and filler dispersion; functional additives for wet grip, rolling resistance and flame behaviour; chemical intermediates; and bonding systems for rubber-to-metal and rubber-to-fibre adhesion.
The company reports spending more than 3% of revenue on R&D, with CNAS-accredited laboratories, a National Enterprise Technology Center recognised in 2019, dozens of patents and a role in drafting national and international standards for the sector. Certified to ISO 9001, ISO 14001, ISO 45001 and IATF 16949, it supplies major global tyre makers and presents its full activity on its official English-language website, through which it serves the worldwide rubber and elastomer market.
