Acrylic
Acrylic or Polymethyl Methacrylate (PMMA) also referred to as its trademark names Lucite and Perspex is one of the most widely used thermoplastics. It is approximately half the weight of glass and has great impact resistance and surface hardness, and unlike glass it is less vulnerable to shattering. It also has great UV and water/salt resistance. Acrylic comes in a wide variety of colours, gloss and transparencies. Acrylic can be easily fabricated, thermoformed, polished and machined.
Applications
Acrylic can be used for screens, aquarium screens, soundproofing, lenses, furniture, and light redirection. Because of acrylics wide range of colours and finishes it is an excellent point of sale material including counter units, brochure holders and signage. Acrylic is also a great substitute for polycarbonate when extreme strength isn’t required.
