Product Information
Optical Brightener OB-1 (C.I .393)
OB-1 is a stilbene benzoxazole class optical brightener suitable for many kinds of plastic materials under high temperature process.
Structural Formula:
Appearance: bright yellow crystals powder
Assay: 98.5%Min Melting point: 355-360ºC
Properties: OB-1 imparts very good heat resistance because of high melting point and strong stability. Because this product`s hydrophobic nature, it has good light fastness. it also has good light-resistance and resistance to bleaching of chloride, can impart excellent effect used in polyester fiber . its strong fluorescence makes it not only can improve substrates whiteness but also brightness, it can be used as disperse dyes in the chemical fiber, can be used like oil dissolving coloring agent in the plastics.
Applications:
OB-1 is Suitable for whitening chemical fibers, such as the polyester fiber, nylon fiber, polypropylene fiber and so on; suitable for whitening and brightening PP, hard PVC, ABS, EVA, polystyrene, polycarbonate, etc, suitable to be added into the conventional polymerization of polyester and nylon fiber, especially suitable for whitening the plastics of high temperature compaction.
Method of usage:
The recommended loading concentrations for plastic and polyester fiber is 0.01 % to 0.05% depending on substrate, processing conditions, and long-term stability requirements.
Please Noted: above recommended loading can be a reference. Exact loading must be
determined by compositions of the specific polymer system
Packing: Packaged in complex paper bags or fiber drums, 25kg each.

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.
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, 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.
