In 1992, we firstly developed and tried to produce Optical Brightener OB.
In 1995, we started to manufacture 2,5-thiophenedicarboxylic acid(also called OB acid) and other kinds Optical Brighteners( OB-1, FP-127, ER) .
In 2005, we started to make Biphenyl series, Optical Brightener CBS-X and Heat Transfer Fluids. the capacity of Biphenyl has been over 6000mt/a. Heat Transfer Fluids can reach 10000mt/a capacity.
In 2012, we started to expand production capacity of some products, such as 5000mt/a diphenyl oxide, 3000mt/a p-toluic acid, 2000mt/a partial hydrogenated terphenyl, 2000mt/a 2-formylbenzenesulfonic acid sodium salts, 600mt/a ferrocene.
After decades fast development, now our products include:
Additives: optical brighteners; Antioxidants; UV Absorbers; Flame Retardants, Photo Initiators, Accelerators; Ferrocene, Etc
Heat transfer fluids: Biphenyl+Diphenyl Oxide Mixture(RFCTHERM-400), Partial Hydrogenated Terphenyl(RFCTHERM-PHT-350), Etc
Intermediates: P-toluic acid, P-Tolunitrile, 2-amino Phenol, Biphenyl, Diphenyl Oxide, 1,4-naphthalene dicarboxylic acid, 2-Formylbenzenesulfonic acid sodium salt, Etc
