Optical Brightener


The plastic materials exposed to light get an undertone of yellow color gradually, and to resolve this issue, chemical materials known as OB are used. This added material that is used on a very limited scale (less than 1 percent) will whiten the surface more, and will result in the better function of pigments in plastics, especially the white pigment.
