Optical Brightener OB-1 is a excellent diphenylethylene bisbenzoxazole type compound.It is unsoluble in water and has stable capability. And it also 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 ideal whitening effect on polyster 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.
APPLICATION Thoroughly dispersed in all those polymers. If any ultra violet spectrum absorption agent is used in the polymers, the optimal dosage of optical brightener OB-1 should be adjusted.
PROCEDUR For transparent product: 0.0025-0.005% Opaque product: ≤0.01-0.03%
