Acrylic

Polymethylmethacrylate (PMMA) is the most commonly used acrylic plastics also known as Plexiglass or Lucite. It is a hard, rigid and transparent thermoplastic with excellent resistance to ultraviolet radiation, weather and most chemicals. Acrylic plastics are extremely strong with high impact resistance. PMMA is an economical alternative to polycarbonate with high durability, clarity, consistent quality, versatility, and excellent performance. Even with its outstanding characteristics acrylics plastics is only half the weight of glass. Acrylics can be easily colored, molded, cut, drilled, milled, engraved or formed. Mechanical and optical properties are not significantly affected due to prolonged exposure to moisture or wet conditions.
