Properties
Optical brightener OB Fine is a kind of benzoxazole compound, it is odorless, hard to dissolve in water, soluble in paraffin, fat, mineral oil, wax and common organic solvents. It can be used for whitening thermoplastic plastics, PVC, PS, PE, PP, ABS, Acetate fiber, paint, coating, printing ink, etc. It can be added at any stage in the process of whitening the polymers and make the finished products emit a bright bluish white glaze.
Application
Optical brightener OB Fine is one of the best brighteners widely used in plastics and fibers and has the same whitening effect as Tinopal OB. It can be used in thermoplastics, polyvinyl chloride, polystyrene, polyethylene, polypropylene, ABS, acetate, and it can also be used in varnishes, paints, white enamels, coatings, and inks.It also has a very good whitening effect on synthetic fibers.It has the advantages of heat resistance, weather resistance, non-yellowing, and good color tone.It can be added to the monomer or prepolymerized material before or during polymerization, condensation, addition polymerization, or added in the form of powder or pellets (i.e masterbatch) before or during the formation of plastics and synthetic fibers.
Reference usage:
1 PVC:
For soft or rigid PVC:
Whitening: 0.01-0.05% (10-50g/100KG material)
Transparent: 0.0001-0.001%(0.1g-1g/100kg material)
2 PS:
Whitening: 0.001% (1g/100kg material)
Transparent: 0.0001-0.001 (0.1-1g/100kg material)
3 ABS:
Adding 0.01-0.05% to ABS can effectively eliminate the original yellow color and achieve a good whitening effect.
4 Polyolefin:
Good whitening effect in polyethylene and polypropylene:
Transparent: 0.0005-0.001%(0.5-1g/100kg material)
Whitening: 0.005-0.05%(5-50g/100kg material)
Package
25kg fiber drum,with PE bag inside or as customer’s request.
