Acrylic Plastic (PMMA)

---

Acrylic (also known as PMMA or Polymethyl-Methacrylate) is an amorphous thermoplastic.

The material offers a high strength-to-weight ratio, is optically transparent and unaffected by water. Often used as an alternative to glass, it should not be considered for structural applications due to the thermoplastic's poor impact resistance. Trade names for Acrylics include Acrylite®, Lucite® and Plexiglass®.

Benefits:

Typical commercial applications include:

• UV-resistant, low-water absorption
• Good insulation properties
• Good stiffness and abrasion resistance
• Clear/colourable - clarity is excellent

Chemical Resistance

Whilst acrylics are not recommended for use with chlorinated or aromatic hydrocarbons, ester or ketones, the material is unaffected by aqueous solutions of most detergents, acids, alkalis and laboratory chemicals.

Applications

Acrylic (PMMA) finds numerous commercial uses including liquid chemical pumps, water tank liners, master cylinders, dashboard lighting, hard contact lenses and helmet visors.

Scratch Resistance

Acrylic offers improved scratch resistance compared to other engineering plastics, which is beneficial as the product comes in transparent or translucent colours. The thermoplastic finds suitability in both engineering and aesthetics-driven applications.
