PS, PC, PBT plastic whitening brightening, with excellent
whitening effect.
-
Suitable for whitening agent
concentrated masterbatch added (such as: LDPE color
concentrate)
Recommended
dosage: every
1000Kg polymer added amount of Optical brightener OB-1:
-
dosage in polyester fiber
75-300g.（75—300ppm）
-
dosage in Rigid PVC
,PP,ABS,Nylon,PC 20-50g.（20—50ppm）.
-
dosage 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
