Extreme UV resistant Plastic?

Extreme UV resistant Plastic?

Extreme UV resistant Plastic?

(OP)
I have been asked to mould a replacement part that is used in a UV sterilizing plant.  The part holds a rubber wiper that cleans the glass UV tube. The part is about 15 mm from the tube so it's getting a really good dose of UV!
The part supplied is made from some kind of fibreglass filled Thermoset.  I don't mould thermosets, so I would like to use a thermoplastic. PVC and PBT have been suggested, but I wonder what is being used in the existing systems?

PMMA is transparent to UV.

Hi Pat, sorry I'm new to the forum and I seem to have posted the question twice.
I have no idea how to get rid of the duplicate.
