Polymethyl Methacrylate/PMMA/ Perspex
Acrylic 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 is a versatile material which can be used in a range of applications but in particular in display and point of sale display purposes. Because acrylic is a semi or fully transparent material it can also be used as a replacement for glass and is often used in aquariums and office applications or even around the home. Acrylic can also be frosted or opal to provide a more private screening material or as a means diffuse light. At Warringah Plastics we mainly use acrylic for signage and point of sale because of its brilliant finish and the wide range of colours that are available.
Colours shown above are just representations of a particular colour and aren’t necessarily the finished plastic colour. Lighting conditions, monitor calibration and variances in the plastic colour processing can impact the colour of a given material. For more information on colour availability please contact us.
