PMMA (Polymethylmethacrylate )

Polymethylmethacrylate (PMMA) is a thermoplastic material formed by polymers of methyl methacrylate, methyl acid methyl ester. It is also commonly referred to using the trade name Plexiglas. From a commercial point of view it is the most important polymer in the acrylic group. It offers excellent chemical and weather resistance. It is a transparent thermoplastic material very similar to Polycarbonate which is used when high impact strengths are not necessary.

Chemical and physical properties:
The formulas vary based on the molecular weight and the required physical properties, such as flow rate, heat resistance and strength. This material is more or less unbreakable depending on its chemical characteristics. High-flow formulas are preferred for molding.
PMMA has excellent optical properties and excellent resistance to atmospheric agents. Transparency in white light reaches 92%, even more than glass. Unlike PC it is very resistant to UV rays and doesn't turn yellow. The molded parts can present a limited bi-refraction, so PMMA proves itself to be a suitable material for video discs. Similar to PMMA is PMA polymethylacrylate which presents as a soft rubber.
PMMA standard density: 1,17 - 1,20 g/cm3 (ISO 1183)
PMMA melting point Tm: 105-160 °C
PMMA glass transition temperature Tg: 80-105 °C

History and Trivia on PMMA:
On the market since 1932, this polymer was of utmost importance during the Second World War when it was used for aircraft glass and submarines. Today it is used in many fields such as aquariums, medical transplants, cosmetic surgery.
Thanks to its very high transparency and its low cost, it has succeeded in many applications to replace glass..
It is curious that the commercial name of Plexiglass - a product developed by the company Evonik in 1933 and still in production today - is better known than the name of the material (PMMA).
