Looking at plastics like UHMW and delrin... wondering how important
is "UV stabilization" for outdoor use? How long does it take for
ultraviolet light to damage the plastic? Months?

If it really matters, is black Delrin most likely to be the UV
stabilized type? Many of them say the color is black but they don't
specify UV stabilization or the specific Delrin part number/type.

Thanks.

Yes, months but varies with your climate and sun exposure. *If it is not
specified with UV inhibitors, don't count on it being there.

If a grade is not specified chances are it can vary or be mixed. *Black
molded parts are the best for getting rig of rejected parts by grinding them
and blending in the virgin material.

Edwin is correct.

If you need UV..and any outdoor usage does...pay the money and get the
right stuff.

Do you really have time to do the the job twice?
