Application: Optical brightener OB-1 is a highly efficient optical brightener used for lanon and widely applied to ABS, PS.HIPS,PA,PC,EVA and hard PVC etc. Its features include admirable whitening effect, excellent thermal stability and very fewer usage amounts.

Usage: Because the little addition of optical brightener, you should separate the brightener drastically, ensure it will be homogeneous distributed in the whole polymer. If you use the concentrated grain, it can be easier to achieve the sufficient dispersion effect.
