Dalian

A Global Leader in Specialty Additives, Intermediates and Heat Transfer Fluids
In 1995 we started to manufacture 2,5-thiophenedicarboxylic acid(also called OB acid) and other kinds of 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 8000mt/a. Heat Transfer Fluids can reach 10000mt/a capacity.

In 2012-2016 we started to expand production capacity and process improvement of some products, the purity of Diphenyl oxide and Biphenyl reach 99.9%, the capacity of p(o,m)-toluic acid is over 6000mt/year. The appearance and purity of o-aminophenyl were greatly improved. Our Heat Transfer Fluid(RFCTHERM-400)was successfully used on CSP project.

Optical Brightening Agent Product Range
Optical brighteners, optical brightening agents (OBAs), fluorescent brightening agents (FBAs) or fluorescent whitening agents are chemical compounds that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and reemit light in the blue region (typically 420-470 nm) by fluorescence. We have a full range catering for the plastics coatings fabric textile detergent and paper industries.
