Azek For racks

Hey guys so i found this material azek thats like xpvc. I was wondering if anyone has used this stuff to build a rack? The lumber supplier im going through does not have xpvc and was wondering if this would be a good alternative?

Make sure that it doesn't put off any fumes and can take the heat (which if should be able too) then I would say go ahead.

Yeah i have heard pvc emits toxic fumes if heated to a certain temp. I cant find any information on this product health related for reptiles or animals. Its not that expensive i can get a 8x4 sheet of 1/2" for 100 bucks.
