Good acrylic is not suitable for burning, and will not produce unpleasant odors during processing. When you buy, you can use their scraps to test. When the acrylic sheet is thermoformed and heated, it is not easy to generate air bubbles and deformation. When the recycled sheet is thermoformed and heated, it is easy to have air bubbles and deformation.
