    A Global Leader in Specialty Additives, Intermediates and Heat Transfer Fluids

    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

    We also focus on inorganic chemicals (Especially in High purity Strontium and Barium salts.

    Today, our products have been exported to many countries, we also have become a global leader in above fields.
