A flat rate of £25 will be applied to any order above the amount of £250; but those below the threshold shall accrue an appropriate courier fee which may take into account location, size and weight.

Cast acrylic, known scientifically as polymethyl methacrylate, is an optically transparent, durable plastic material with diverse applications in many industries. The physical properties of cast acrylic make it an ideal material for many uses including arts and crafts, furniture production, visual communications, signage fabrication, point-of-purchase displays, and many other applications. 

Known for its clarity and excellent optical properties, cast acrylic is an optically transparent thermoplastic with exceptional stiffness, strength and resistance to UV radiation. Cast acrylic is lighter in weight than other plastics (like glass and polycarbonate) making it easier to fabricate and transport. Acrylic features an exceptionally low coefficient of friction, making it an excellent material for applications involving sliding and gliding components. 

Cast acrylic is created by pouring the raw polymer pellets into a mold and heating the pellets to the desired melting point. The mold is then allowed to cool and harden, resulting in the desired shape of the acrylic material. One of the benefits of cast acrylic is that it can be customised to fit specific shapes and sizes that can’t be accomplished with other plastic materials. It can also be easily designed and configured with high levels of precision. 

On a molecular level, the acrylic monomers are cross-linked which makes it resistant to a wide variety of organic solvents, chemicals, and other aqueous solutions. This provides the desired level of chemical resistance that cannot be met with other types of plastic resins. Cast acrylic has a wide range of temperature tolerances, allowing it to be used in indoor and outdoor environments at temperatures ranging from 32°F to 180°F. 

Cast acrylic is also easily machinable, making it possible to create parts with various shapes and sizes. It can be cut, bent, drilled, milled, routed and carved. Furthermore, cast acrylic is highly polishable and can be aesthetically machined to meet the specific requirements of any application. 

Ultimately, cast acrylic provides the desired combination of mechanical, optical and chemical resistance properties in one material. It can be swiftly transformed to suit a variety of applications with its low temperature thermal bending, high refractive index, optical clarity and chemical resistance. The availability of custom colours and grades gives designers the freedom to have their products uniquely finished and branded. With its outstanding performance and properties, cast acrylic is the go-to option for countless applications.
