Solubility : insoluble in water,but
soluble in high boiling point organic solvent such as phenyl-chloride
Properties & Features：
①Whitening high strength, strong
fluorescence.
②Wide applicable performance, widely used in
polyester fiber (such as: polyester fiber, nylon fiber whitening) and many kinds
of plastic whitening.
③Excellent thermal stability and very fewer
usage amounts.
Range ofApplication:
①Suitable
for polyester fiber (PSF), nylon fiber and chemical fiber whitening.
②Applicable
to PP, PVC, ABS, PA, PS, PC, PBT plastic whitening brightening, with excellent
whitening effect.
③Suitable
for whitening agent concentrated masterbatch added (such as: LDPE color
concentrate)
Recommended
dosage:every 1000Kg polymer added amount of Optical
brightener OB-1:
①dosage in polyester fiber 75-300g.（75—300ppm）
②dosage in Rigid PVC
,PP,ABS,Nylon,PC 20-50g.（20—50ppm）.
③dosage
in whitening concentrated masterbatch 5-7kg.（0.5—0.7%）.
Note:For PE and
soft PVC using fluorescent Optical brightener OB-1, special attention should be
paid to the amount of control, excessive dosage will happen brightener
migration. Add any UV absorber in the polymer, the best dosage should pay
attention to adjust Optical brightener OB-1
Handling and Storage:
As with
all industrial chemicals, use good industrial practices when handling. Avoid
eye, skin, and clothing contact.Do not inhale. Do not taste or swallow. Use
only with adequate ventilation. Keep container tightly closed in a dry, cool
and well-ventilated place.
Packaging：25KGS fiber drums within double PE
bags；Or according to user requirements
