GENERAL PROPERTIES Ardel® PolyArylate D-100 offers outstanding performance characteristics when exposed to environments that contain ultraviolet lighting. This polymer has shown a better retention of gloss, lower haze and light transmission in accelerated aging testing than polycarbonate. The 8000 hour test conducted on polyarylate showed only a slight loss in properties when compared to a 2000 hour test and 90 percent loss of the original notched Izod strength with polycarbonate.
Ardel® PolyArylate outperforms many other engineering thermoplastics with with a HDT measured value of 345°F (174°C) at 264psi and an Underwriters Laboratory RTI (Relative Temperature Index) of 266°F (130°C) for electrical and mechanical properties.
