Poly(methyl methacrylate), or plexiglass, was found to react to ethanol when used in high concentrations. When our fiber bending tank (made of poly) was being cleaned with pure ethanol, an obvious reaction was seen as crazing developed on the surface of the walls of the tank. Because our fibers are made from a similar material (polystyrene with flour-acrylic cladding) it seemed necessary to also test their reaction to exposure to alcohol. | Poly(methyl methacrylate), or plexiglass, was found to react to ethanol when used in high concentrations.
