Introduction:
OB is a thiophenediyl benzoxazole class optical brightener suitable for various thermoplastic polymers, painting ink, coating, paint.
Structural Formula:
Details :
CAS No: 7128-64-5
Appearance: light yellow or milk white powder
Assay: 99%Min Melting point: 201-202ºC
Properties:
1. Small consumption, strong whitening intensity, small consumption can bring a very good whitening result.
2. Wide service behavior, suitable for various kinds of plastic whitening.
3. Have a good compatibility with plastic, good resistance to high temperature and excellent light fastness and weathering resistance.
Applications:
OB as an excellent brightener has been used in various thermoplastics including PVC, PS, PE, PP, ABS, Polyolefin and other organic materials, It can also be used in coating, paint and ink, has good compatiblity with many substrates, has been widely used in plastic industry because of good heat-resistance, low addition amount and exceptional whitening effect. It shows special bright shade combined with some dyes. it is suitable for food packing but local regulations must be observed.
Method of usage:
The recommended loading concentrations for light color polyolefin is 0.0005 % to 0.0010% and the loading levels in other plastics range between 0.005% and 0.100% depending on substrate, processing conditions, and long-term stability requirements. When OB is used with UV absorbers, pls noted, the loading levels must be increased.
Please Noted: above recommended loading can be a reference. Exact loading must be
determined by compositions of the specific polymer system
Packing: Packaged in 25kg complex paper bags or fiber drums.

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.
