Product application

LEPUZ Optical Brightener OB-1 is a excellent diphenylethylene bisbenzoxazole type compound. It is unsoluble in water and has stable capability. And it also has good resistance to heat, sunlight, chlorine bleaching and migration. It owns especially high temperature tolerance, suitable for shaping various kinds of plastics and their products under high temperature. It has an ideal whitening effect on polyester fibers as well as polyester fiber-containing fabrics including polyester-cotton blend fabric. It can be used to whiten various kinds of plastics such as ABS,PS,HIPS,PA,PC,PP,EVA and rigid PVC.With addition of optical agent OB-1, polyamide fiber, nylon and polyester have significantly good whiteness. Mixed with this product, recycling polyester waste material, bottle material and slice flake will have a higher whiteness than before, and recycling materials will have better similar color.

1. for the whitening of polyester fiber, nylon fiber and polypropylene fiber
2. for the whitening of polypropylene plastics, hard PVC, ABS, EVA, polystyrene and Makrolon
3. to be used in polyester and nylon.

DOSAGE
The recommended dosages in per 1000Kg raw material are as follows,
1. For EVA, PP fiber, nylon, PC, PVC, etc: 75-200 grams.
2. For polyester fiber: 75-300 grams.
