Plastic efficient optical brightener OB-3
RITAN
3204200000
Plastic efficient optical brightener OB-3
Technical Indicators
Appearance: yellow-green powder
Purity: ≥97%
Melting point: ≥350°c
Volatile: ≤0.5%
Characteristics and usage:
It has a good thermal stability(≥375°c), and could apply to molten plastic.
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.
It is applicable for various polymer and recycled of polymer, and it could significantly promote the whitenss of recycled polymer and improve the recycled polymer value.
It can reduce the yellowish of polymer through the fuction 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.
Method of use:
25-300PPM in new polymer and 300-400PPM for recycled material.
Packaging: 25KGS Fiber drums within double pe bags.
