Appearance: Powder

Melting point: 233-235 ℃

Content: ≥ 99.2%

Product features and applications:

Fluorescent whitening agent OB-T belongs to the coumarin class compounds, with a light yellow crystalline powder appearance, a melting point of 233 ° C, insoluble in water, odorless, and stable performance.

Usage: Mainly used for whitening plastics, colorants, rubber, polyester, polyamide, and polyacrylonitrile fibers. For example, plastics such as PVC, PS, ABS, PE, PP, etc., due to their superior fluorescent whitening effect, good thermal stability, and low addition amount, the fluorescent whitening agent OB-T can be used together with dyes to produce special brightness, which is particularly effective in color formulations.
