PMMA Properties, Production, Price, Market and Uses

Poly (methyl methacrylate) is a form of non- degradable polyacrylate widely being used for optical components of a high level of clarity & structural rigidity.


What is PMMA?

Polymethyl methacrylate is a synthetic resin produced by the polymerization process of methyl methacrylate. It is a kind of transparent, rigid and clear plastic used commonly as shatterproof replacement of glass (windows, skylights, laminated signs & aircraft canopies etc).

This material has proved to be an economical alternative for polycarbonate when tensile strength, transparency, polishing & UV resistance is more important than impact strength and resistance to chemicals & heat.

It is preferred material over polycarbonate as it does not contain harmful bisphenol- A, which is a sub unit found in polycarbonate materials. This resin is also considered over others due to its moderate properties, ease of handling & processing along with its low cost.


It was first discovered by British chemist Rowland Hill & John Crawford at Imperial Chemical Industries (ICI) in England (the year 1930). ICI registered the product under the trademark of Perspex.

At the same time, Otto Rohm (chemist & industrialist) in Germany attempted to produce safety glass by polymerization of methacrylate between the two layers of glass.

As a resulting polymer separated from glass providing a clear plastic sheet which was given the trademark of Plexiglas. Both the products entered the commercial market in the late 1930s

Later, E.I. du Pont de Nemours & Company (now DuPont) in the U.S introduced their own product under the trade name of Lucite.

Major Application – During World War II, when aircraft windows & bubble canopies for gun turrets were made using PMMA.


This form of material is one of the members of huge methacrylate esters family with an attached group of Alkyl or Aryl. It is commonly produced by emulsion polymerization, solution polymerization & bulk polymerization.

PMMA material is an ester of methacrylic acid, which belongs to an important acrylic family of resins. It is primarily obtained by propylene (compound refined from light fractions of crude oil) used in production process.

Further, propylene & benzene are reacted together to produce cumene or isopropyl benzene. Afterwards, the produced cumene is oxidized to cumene hydroperoxide.

Then, it is treated with acid to produce acetone which is further converted to methyl methacrylate (flammable liquid). This liquid is polymerized in form of bulk liquid or suspended fine droplets of water under influence of free radical initiators to form solid (PMMA plastic)

It is majorly sold under the trademarks of Plexiglas, Lucite & Perspex.


Basic properties of this plastic material which make it an ideal choice to be highly used as a substitute for glass and for various other uses are:

  • It is a strong, tough and lightweight material.
  • Has better impact strength than both glass and polystyrene.
  • Superior environmental stability as compared to other plastics.

What are disadvantages of using PMMA material?

As compared to other substitute plastic materials it has low impact resistance & strength. Sometimes it can experience some brittle failures as it is not that strong and may crack without bending.

Is PMMA toxic?

This polymer material has one of the major advantages over other forms of plastic polymers as it does not contain or release Bisphenol A (BPA) during the process of hydrolysis.

Even the related plastic material which is polycarbonate contains BPA which makes it toxic in nature. Some studies prove that BPA is hazardous to health & environment.

It has resulted in the formation of “BPA-Free” kind of polycarbonates products (canning jars) whereas PMMA in itself is a BPA-Free kind of plastic that is non-toxic in nature when it is in its solid form.

Usually, fumes emitted during 3-D printing ore when used in a molten form for injection molding can prove to be toxic. It should be well ventilated during its manufacturing process to avoid inhaling, as it can result in health risks.
