Product Description

                                                                                   --  Optical Brightener OB--
 

Optical brightener OB-1 is an efficient fluorescent whitener

for polyester fibers, and is widely used in ABS, PS, HIPS, PA

(nylon), PC (polycarbonate), PP, EVA and rigid PVCplastics.

Because the amount of whitening agent added is small, it should

be thoroughly dispersed so that the whitening agent can be

evenly dispersed in the entire polymer. If the whitener is used to

concentrate the masterbatch, the dispersion effect is easier to

achieve. When Optical brightener OB-1 is used for PE and soft

PVC, special attention should be paid to the control of the

dosage, because excessive dosage will cause whitening

agentmigration.
