Doesn't say, but it sure looks and feels like PVC.

I would have guessed ABS. There are adhesives that will
work for both. You might try taking a small piece of
ABS or PVC to make a patch and get an adhesive that works
with both to glue it in.. Weld-On 1007 would work, but the
patch would have to be a close fit.
