When you need a durable plastic material for your own use or application, you almost certainly need the polycarbonate or acrylic sheet. With regards to impact resistance and strength, you already know polycarbonate wins by large.
Below, we break down the professionals and cons of each and provide some common acrylic applications for every type of plastic. If you are searching for new eyeglasses, be sure to ask about all of the lens materials available. After that you can apply the info you have learned here to determine which lens type best suits your preferences.
