Product Description
1. Technical indicators:
Appearance: yellow-green powder
Purity: >=97%
volatile: <=0.5%

2. characteristics and applications:
1.It has a good thermal stability (>=375°C),and could apply to molten plastic.
2.It is widely used in the market of polyester fiber to reduce the degree of changing-to-yellow and it could increase the whiteness & brightness .Being the good whitening ability and stability ,it can be compatible with many polymers with various properties .Now it becomes to a efficient brightening agent for many plastic products.
3.It is applicable for various polymer and recycled of polymer, and it could significantly promote the whiteness of recycled polymer and improve the recycled polymer value.
4.It can reduce the yellowish of polymer through the function of absorbing ultraviolet radiation and the effluent blue resent. For example, under the action of TiO2,it will effect the bright white appearance. The white enhancement factor contained in OB-3 can effect in polymer and make bluer white more than OB-1.
