Of course, various materials and plastics have different qualities that can both lend themselves to specific operative environments as well as impact cost. In today’s blog post we offer a complete guide to acrylic in “What is cast acrylic”.

What is acrylic?

Firstly, what is acrylic? Well, depending on where you are in the world acrylic can have various names and meanings. Cast acrylic is a form of poly(methyl methacrylate) which itself is transparent thermoplastic that is often used as a lightweight and shatter proof alternative to glass. Cast acrylic is formed through a casting process where a monomer, methyl methacrylate, is mixed with initiators. A monomer is a substance that causes a reaction and polymerises into the polymer. Acrylic has many names and is also known as Lucite, Acrylite, Pexiglass and PerClax amongst others. Acrylic sheets and rods are made by casting into casts whilst acrylic tubes are done through molds that rotate using the centrifugal force to push the material into position.

What are the properties of cast acrylic?

Cast Acrylic has excellent durability and optically clear transparency and lends itself to a wide scope of uses such as in acrylic tubes and other commercial and architectural uses. Whats more, cast acrylic is much more common than you may realise and is used in mobile phone displays, cars and even furniture design. 

What is Acrylic Casting?

Acrylic casting  refers to the  technique of plastic casting where the mold is filled with liquid synthetic resin that then hardens. This means the literal pouring of liquids into sculpted molds to create a final shape.
