Is Ryton PPS suitable for use in applications where it is exposed to ultraviolet (UV) light?
Although exposure of Ryton PPS to UV light may cause some surface degradation, the properties of the bulk material will be relatively unaffected. Several Ryton PPS compounds (R-4, R-4 02, R-4XT, R-4 02XT, R-7 02, R-10 5002C, and R-10 7006A) have been rated suitable for outdoor use with respect to UV light exposure, water exposure and water immersion, in accordance with UL746C.
