What's Optical Brightener OB-1?
Optical brightener a kind of fluorescent dye, or white dye, and it is also a complex organic compound. Its characteristic is that it can excite incident light to produce fluorescence, so that the dyed material can obtain a sparkling effect similar to fluorite, and the material that is seen by the naked eye is very white.
Optical Brightener OB-1 Application:
Optical brightener ob-1 is the most ideal brightener for recycled plastics and recycled polyester fibers, with a small amount of addition and superior whitening effect
Optical Brightener OB-1 Advantage:
1. High whitening intensity and strong fluorescence.
2. Wide application performance, widely used in whitening of polyester, nylon fiber and various plastics.
3. Excellent high temperature resistance.

FAQ:
For optical brighteners, the program encourages manufacturers to use those that pose "low toxicity to humans and the environment both as parent chemicals and degradation byproducts." Optical brighteners aren't readily biodegradable and may bioaccumulate, so they pose a potential hazard to aquatic life.
