Fluorescent whitening agent OB-W belongs to the benzothiazole class compounds, with a light yellow crystalline powder appearance, a melting point of 233 ° C, insoluble in water, odorless, and stable performance. Application of polyacrylic acid: mainly used for whitening plastics, colorants, rubber, polyester, amine, 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 0B-W can be used together with dyes to produce special brightness, which is particularly effective in color formulations.

Usage:

Due to the small amount of fluorescent whitening agent added, it should be thoroughly dispersed to ensure that the whitening agent can be evenly dispersed throughout the entire polymer. If whitening agents are used to concentrate the masterbatch, it is easier to achieve sufficient dispersion effect.

characteristic:

-Has good thermal stability, special whitening performance, good photostability, and low volatility

-Non toxic and odorless

Not reacting with foaming agents and crosslinking agents

Packing： (25 kg × 1) Fiber drums.
