except polycarbonate will yellow with uv
You can get uv resistant grades but they will still yellow eventually
I think its softer too so scratches easier
Not an expert but Lexan is used for motorcycle helmet visors and I've never had one 'yellow'; they have to be scratch resistant too.
Its sun that does it
Your van unless garaged gets all the hours of sunlight after several years even uv resistant grade polycarb will yellow
Your motorcycle helmet spends most of its life out of sunlight
Scratch resistance is relative glass is good hard plastics next soft plastics worse
I believe a security cam attached to my pc recording 24/7 is the answer. A warning sign in the van window will hopefully draw the miscreants attention to the camera on the wall and dissuade them.
Both breakages have happened in "school run" hours, with a large secondary school about 1/4 mile down the road. Hence any video images can be presented to the Head of the school for identification purposes.
I'm not intending the plastic to be a permanent solution so yellowing is not an issue. In fact I am tempted to use uPVC foam board, sprayed matt black, to reduce the cost.

I have a spare rear screen in my loft I can do a template for you if you still require one. I would love to be able to say you could have the screen but alas its a factory blue tinted one waiting to go in my van

If Pac-Man affected us as kids, we'd all be running around in darkened rooms, munching magic pills and listening to repetitive electronic music

Gotta be careful filming kids these days, might get your self a reputation...
Might be a bit late on this one, looking for some lexan for my own little project and discovered they now manufacture a UV resistant type in regards to the yellowing problem, its called lexan XL102UV
hope you catch the buggers
