Acrylic polymers (PMMA)
Description (definition)
Acrylic polymers, often known as polymethyl methacrylate (PMMA), are thermoplastics characterized by their high transparency, weather resistance and excellent optical properties. PMMA is known by brand names such as Plexiglas or acrylic glass and is often used as a lightweight, shatterproof substitute for glass. It is widely used in areas such as construction, the automotive industry and medical technology.
Example
A classic example is the use of PMMA in the manufacture of car lights. Its high light transmission and scratch resistance make it ideal for clear and durable covers that meet the requirements of modern vehicles.
What are the advantages of acrylic polymers compared to glass?
Acrylic polymers such as PMMA are lighter and more shatterproof than glass, which improves their handling and safety. They also offer better UV resistance and can be produced in different colors and shapes. This makes them particularly suitable for applications such as billboards, glazing and design objects.
Where are acrylic polymers frequently used?
PMMA is used in the construction industry for windows, roofs and partition walls. In the automotive industry, they are used for rear lights, covers and interior fittings. Acrylic polymers are also used in medical technology for optical lenses and dental products.
Is PMMA recyclable and how is it recycled?
Yes, PMMA is recyclable. It can be mechanically shredded and reprocessed or chemically broken down into its monomers to produce new PMMA. Recycled PMMA is often used in less visible applications such as housings or substructures.
