Stock shapes extruded from Ardel® resin are specifically formulated to endure the damaging
effects of UV light. When exposed to UV light, this unique material undergoes a molecular
rearrangement resulting in the formation of a protective layer that essentially serves as a UV
stabilizer. This inherent UV stability combined with superior retention of optical and mechanical
properties make polyarylate an ideal choice for any application where weathering effects could
pose a problem.
The following physical property information is based on typical values of the base Ardel® polyarylate
resin (PAR).
