Različita imena za PO pjenaste kotače

As a newcomer who has recently started working in the factory，I was shocked that there are many different names for foam-filled wheel, just like PU Foam Wheel,PU Foam Filled Solid Tyre,PU Tyre,Plastic Wheel,Polyurethane Wheel,PU Flat Free Wheel,Foam-filled Tires,Puncture Proof Plat Free PU Foam Wheel,Urethane Solid Foam Wheels,Flat-free Polyurethane Foam Wheel,PU Wheels,Polyurethane Wheels itd

Najčešći izraz koji ovdje koristimo je PE pjenasti kotač. Kako ga tamo zovete?
