Choose by material and process
The suitable fluorescent whitening agent depends on the polymer or formulation, processing temperature, dispersion, colour target and any other UV-active additives.

Describe the current colour, required whiteness or blue shade, opacity and end-use appearance.
Commercial requirement
Include trial quantity, regular demand, packaging preference and destination port or city.
Frequently asked questions
Which AOBO optical brightener is suitable for plastics?
The choice depends on the resin, process temperature, dispersion and colour target. OB-1 is listed for several polyester and plastic applications; other grades cover different polymers and formulation needs.
Can one dosage be used for every polymer?
No. The suitable addition level depends on the material, opacity, formulation and target appearance. Small-scale trials should be used to confirm the level.
What details help AOBO review a grade?
Send the base material, process temperature, existing additives, target appearance, trial quantity and destination.
