Linsorb UV 234
|Appearance||slightly yellow powder or granules|
|Melting point||137 – 141 °C|
>Features of uv 234 are low volatile benzotriazole UV absorber, high molecular weight, used as tinuvin 234 equivalent.
>Tinuvin 234 exhibits high absorbance in the 300–400nm region and minimal absorbance in the visible region of the spectrum.
>Especially suited for polycarbonates, polyesters and other polymers usually processed at high temperatures. In polyolefins, it has low volatility at high temperatures and high resistance to thermal degradation for polyolefin compounding and molding applications. It is especially suitable for applications of high surface area, such as films and fibers.
>UV 234 can be used alone or in combination with other additives such as HALS and antioxidants.
>Use levels of UV 234 range between 0.15 and 0.60 %, depending on the substrate and performance requirements of the final application.
Handling and Safety:
>Tinuvin 234 exhibits a very low order of oral toxicity and does not present any abnormal problems in its handling or general use.
>For additional handling and toxicological information, please consult us for Maternal Safety Date Sheet.
