UVSOB 234 belongs to the family of substituted benzotriazoles which protects against ultraviolet radiation.
UVSOB 234 has a low volatility, which makes it especially useful for applications involving high temperature processing.
UVSOB 234 is suitable for polymer production where additive losses may occur during high temperature processing.
UVSOB 234 has been widely used in areas like coating for automobile paint, PET fiber and film, PC, POM, Nylon and TPE compounding.
A percentage of 0.1 % - 0.5 % of UVSOB 234 is recommended for protection.
Light stability of polymer can be further enhanced by the use of a phenolic antioxidant and a hindered amine light stabilizer in the combination with UVSOB 234. |
