| | Acrylic |
 | | Acrylics (Polymethyl-Methacrylate or PMMA) is an amorphous thermoplastic which is optically transparent, unaffected by moisture, and offers a high strength-to-weight ratio. |
 | | Acrylics are unaffected by aqueous solutions of most laboratory chemicals, by detergents, cleaners, dilute inorganic acids, alkalies, and aliphatic hydrocarbons -- however, acrylics are NOT recommended for use with chlorinated or aromatic hydrocarbons, esters, or ketones. |
 | | Acrylics are available in colorless clear as well as a wide variety of colors and tints. |
