PMMA plastic
PMMA plastic: properties, use and differences to acrylic glass
Which plastic is PMMA?
PMMA stands for polymethyl methacrylate, which is also known as acrylic glass or Plexiglas. It is a transparent thermoplastic that is widely used for its optical clarity, hardness and versatility.
How do I recognise PMMA?
PMMA is easily recognised by its transparent and crystal clear appearance. It has a smooth surface and can be produced in a variety of colours. In general, PMMA is characterised by high light transmission and brilliant optical properties.
What is PMMA used for?
Architecture and construction: PMMA is used to make windows, cladding, skylights and other architectural elements.
Automotive: PMMA is used for car windows, headlight covers and interior trim.
Advertising and display: PMMA is used for billboards, displays, shop windows and exhibition stands.
Medical: Due to its transparency and biocompatibility, PMMA is used for medical devices such as disposables, prostheses and optical lenses.
Art and design: Artists and designers use PMMA for sculptures, furniture, lighting and other creative projects.
Is acrylic glass PMMA?
Yes, acrylic is another name for PMMA. It is the same plastic. Acrylic is the colloquial name used because of its similarity to real glass. Plexiglas is a trademark for acrylic glass and is often used synonymously.
Differences to real glass:
- Weight: Acrylic is lighter than glass, which makes it easier to transport and install.
- Shatter resistance: Acrylic glass is more shatter resistant than glass and does not shatter under strong impact.
- Machinability: Acrylic is easier to cut, drill and shape than glass.
- Transparency: Acrylic offers high light transmission, but can yellow easily with prolonged exposure to UV radiation.
Summary
PMMA, also known as acrylic or Plexiglas, is a versatile and transparent plastic used in many fields due to its optical clarity, hardness and versatility. From architecture to the automotive industry to medical technology, PMMA has numerous applications. It is easy to recognise and differs from real glass in some aspects. The use of PMMA makes it possible to realise aesthetic and functional projects.
