Company Profile
A Global Leader in Specialty Additives, Intermediates and Heat Transfer FluidsIn 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. In 2012, we started to expand production capacity of some products, such as 5000Mt/a DIPEHNYL 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, EtcIntermediates: P-toluic acid, P-Tolunitrile, 2-amino Phenol, Biphenyl, Diphenyl Oxide, 1,4-naphthalene dicarboxylic acid, 2-Formylbenzenesulfonic acid sodium salt, EtcHeat Transfer Fluids: Biphenyl+Diphenyl Oxide Mixture(RFCTHERM-400), Partial Hydrogenated Terphenyl(RFCTHERM-PHT-350), 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.A Commitment to Our ProductsAll our products are supported by our Quality System and testing and R&D laboratories, we offer expert technical support and valuable services based on our professional knowledge over decades, We apply this approach to create a customer experience that is friendly, efficient and seamless, We hope to establish good cooperation relations with colleague worldwide.A Philosophy of Sustainable and Innovative DevelopmentWe always select environmentally responsible raw materials to manufacture our products, For every product across our entire product line, we constantly looks for ways to reduce environmental impact, everybody is obliged to pr[ Buying Categories ] - Chemicals >> Other Chemical Auxiliaries
