Acrylic Plastic Properties

by acrylic on October 7, 2012

Polymethylmethacrylate (PMMA) is the technical term for Acrylic plastic. The properties of this great product are:

  • Resistant to inorganic acids
  • Extremely rigid
  • 7,000 psi is the tensile strength
  • Transparent (if it is made “clear”) with good Ultra Violet Resistence
  • Suitable to use in temperatures up to 70 degrees Celsius
  • Max Temp is 90 degrees Celsius (short periods only, not continuous)
  • 100 degree Celsius is the melting point
  • High Heat Resistance
  • R120 (Hardness)
  • Solvent Bond-able
  • High Impact Resistance

With the above properties, PMMA is an excellent choice if you are planning on making or buying a custom product, such as a picture frame, fish tank, cabinet, or shelving. Polymethylmethacrylate in a thickened form is great shield against beta radiation, but you have to get a thick piece of it to do so. It comes in every color of the rainbow. Since it forms easily, and is bendable, you can get it in any shape. If you want to give it a “glass” like finish, you can flame polish it.

Another advantage of using acrylic, is that it is extremely strong. In the event that it breaks or gets damaged, it will not shatter. This is because of the way the polymers are formed during production. It will break into large pieces, and this makes it a safe product to use in many applications.

This product is also used in medical procedures and devices. Hard contact lenses are usually made from this substance. Do you wear dentures?  If so, then you have it in your mouth right now. The same is true with dental fillings. If your filling is made of a composite, then it should have PMMA in it. It is also used in many cosmetic procedures, as a component in a filler. These fillers are used to smooth out the skin and eliminate wrinkles.
