Product Name:Optical Brightener OB-X

Appearance: Powder

Melting point: 233-235 ℃

Content:>99.2%

Product features and applications:

Optical Brightener OB-X 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 Optical Brightener OB-X 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, the whitening agent should be thoroughly dispersed so that it can be evenly dispersed throughout the entire polymer. If additive concentration masterbatch is used, it is easier to achieve sufficient dispersion effect,

characteristic:

1. Has good thermal stability

2. Special whitening properties

3. Good photostability and low volatility

4. Non toxic and odorless

5. Do not react with foaming agents or crosslinking agents

Packing： (25 kg × 1) Fiber drums.
