Interesting. They used to be polyurethane mixes.

PMMA is plain old acrylic. Your taillight lenses are acrylic.

If you buy a tub of macaroni salad from the grocery store, its lid will be
polypropylene. Those corrugated plastic promotional pole signs you see at
gas stations are also polypropylene.

I wonder why they switched materials?
