Applications:
UV-P is a benzotriazole type UV
absorber. Characterized by its strong, broad range UV absorption
property, UV-P brings an excellent photostability to polymers
against UV light exposure in many ways i.e. retarding color
yellowing , preventing embrittlement, maintaining of mechanical
properties etc.
* Styrenic polymers: 0.**0.5wt%

ADVANTAGE
* Very high photostability for
its strong ability to absorb light especially in UV
region(******0nm)
* 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.
Stability and
Storage:
In a closed system and dry, dark
place without any light exposure.
