Ultimate UV resistant plastic?
Ultimate 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?

I am told that the UV emitted is UV(c) not the usual A and B, I don't know if this has any effect.
I was just thrown by the fact that the original suppliet had used a fancy thermoset.
