PMMA: Polymethyl methacrylate (Acrylic) or Plexiglas

Polymethyl methacrylate (PMMA), also known as acrylic or Plexiglas, is a transparent, rigid and lightweight thermoplastic material widely used for its excellent optical properties and ease of manufacture. Here is an overview of the main characteristics and applications of PMMA.

Main features

Transparency: High optical transparency with light transmission of around 92%, similar to that of glass.
UV and weather resistance: Excellent resistance to UV rays and weather conditions, does not yellow over time.
Mechanical resistance: Good mechanical resistance, although less impact-resistant than polycarbonate.
Lightweight: Approximately half the weight of the glass, making it easy to handle and install.
Easy to make: Easy to cut, shape, drill and glue.
Chemical resistance: Good resistance to many chemicals, but may be affected by some organic solvents.
Thermal properties: Maximum operating temperature approx. 80°C to 90°C.
Thermal and acoustic insulation: Good thermal and acoustic insulation.

Applications

PMMA is used in a variety of industries and applications because of its transparency, lightness and weather resistance.

Signage and display industry: Signs, billboards and protective screens.
Construction industry: Windows, skylights, roofs and safety glazing.
Medical equipment: Lenses, medical devices and protective cases.
Automotive and transport: Motorcycle windscreens, vehicle windows and lighting.
Design and decoration: Furniture, aquariums, objets d’art and displays.
Optics: Camera lenses, eyeglasses and optical instruments.

PMMA is valued for its unique combination of optical properties, durability and ease of manufacture, making it a versatile and reliable material for many industrial and commercial applications.
