JapanBargain1932 Bowl Dish Holder, Plastic, White

Does anyone use this tray in dishwasher with heating element in use?

Plastic? Does anyone know what kind of plastic?

Does this dish holder get hot ? Would it get to hot Handle after use in microwave?? Does these dish holders come in colors and sizes???

What is the diameter of the plate holder? I recently purchased a 13" in diameter that was too big for my mic and am looking for something smaller
