Details

Other names: TINUVIN 770; EVERSORB 90

Appearance: White crystals

Solubility: Clear solution, free from insoluble

Wahi wā huakaʻi: 82-86

Volatiles content:0.5% max

Ash content: 01 % max

Transmittance: 425nm 98.0% min

500nm 99.0% min

UV-770 can be dissolved in such organic solvent such as benzol, touene, phenyethene, etc. It can not be dissolved in water. It can be easily dissolved in som kinds of resin, and it is not sensitive to metal Ions. Under alkalinity, as low volatile, it is not turned int yellow, ca absorb the ultraviolet ray of 270-380nm wavelength effectively. When used with antioxidants, it has cooperative effect. With lower position, it is considered as the world's sagest plastic accretion.
