STRUCTURE:
PROPERTIES:
Optical Agent OB-1 is a excellent diphenylethylene bisbenzoxazole type compound. It is unsoluble in water and has stable capablity, also it has good resistance to heat, sunlight, chlorine bleaching and migration. It owns especially high temperature tolrence, suitable for shaping various kinds of plastics and their products under high temperature.It has an extra ideal whitening effect on polyester fibers as well as polyester fiber-containing fabrics including polyester-cotton blend fabric It can be used to whiten various kinds of plastics such as ABS, PS, HIPS, PA, PC, PP, EVA and rigid PVC. With addition of Optical Agent OB-1,polyamide fiber, nylon and polyester have significantly good whiteness. Mixed with this product, recycling polyester waste material, bottle material and slice flake will have a higher whiteness than before, different, recycling materials will have better similar color.
USEAGE:
Optical Brightener OB-1 should be thoroughly dispersed in the polymers. When an ultra-violet absorption agent is added, the optimal dosage of optical brightener OB-1 will be adjusted accordingly.
DOSAGE:
For transparent 0.0025-0.005% opaque ≤ 0.01-0.03%
STORAGE：
Should be stored in cool and dry place.
