- Advantages
*Very high photostability for its strong ability to absorb light especially in UV region(290～400nm).
*Odorless,does not bring smells to the polymers.
*Very stable to heat, and can be used in plastics which require high processing temperature.
*Low vapor pressure, very little or no loss during processing.
*Very good compatibility with thermoplastic polymers offering homogeneous distribution during processing.
