PMMA Acrylic

Engineering Plastic

Acrylic PMMA Engineering Plastic

Acrylics (Polymethyl-Methacrylate or PMMA) is an amorphous thermoplastic which is optically transparent, unaffected by moisture, and offers a high strength-to-weight ratio. Common trade names for this material include Plexiglas®, Acrylite® and Lucite®.


Acrylics are not recommended for use with chlorinated or aromatic hydrocarbons, esters or ketones. However, the material is unaffected by aqueous solutions of most detergents, acids, alkalies and laboratory chemicals. It is both a thermoplastics and transparent plastic and is often used as an alternative to glass, but should not be used in structural applications due to low impact resistance.

Typical Applications

Commercial applications for this engineering material include:

  • Master cylinders
  • Water tank liners
  • Liquid chemical pumps
  • Dashboard lighting
  • Motorcycle helmet visors
  • Hard contact lenses

We stock Acrylic (PMMA) in plate and sheet.
