additives for recycled PET bottles
(OP)
I'm developing an indoor fixture to be made of recycled PET bottles. One thing I noticed about PET bottles is that they get brittle and disintegrate after a number of years even without UV exposure. Is there an additive that can be used to mitigate this?

And where did you see this phenomenon?
PET (without UV, which it is rather good at) should be good for several thousand years - hence the drive to recycle the stuff!

Once it has fillers, or any UV opaque colours or any stabilisers, it can last many decades in direct sunlight.
You need to do your own homework re available stabilisers to meet your needs.
