Ardel® Polyarylates are a family of aromatic polyesters. Its inherent UV stability combined with superior retention of optical and mechanical properties makes Ardel® an ideal choice for any application where weathering effects are an issue.
By comparison, the basic mechanical properties of PAryls are similar to polycarbonates. Its impact strength is similar to medium-impact ABS. The elastic rebound of PAryls is exceptional which makes it a logical candidate for snap-fit applications.
Ardel® is specifically formulated to endure the damaging effects of UV light. When exposed to UV light, this material undergoes a molecular rearrangement resulting in the formation of a protective layer that essentially serves as a UV stabilizer. This polymer has shown a better retention of gloss, lower haze and light transmission in accelerated aging testing than polycarbonate.
