Polymethylmethacrylat (PMMA)
Description (definition)
Polymethyl methacrylate (PMMA), also known as acrylic glass, is a transparent, thermoplastic material. It is characterized by its high light transmission, scratch resistance and weather resistance. PMMA is lighter and more break-resistant than glass and is often used as an alternative to conventional glass in the automotive, construction and electronics industries as well as in advertising.
An example
A classic example is the use of PMMA in the automotive industry for rear lights. Its high transparency and weather resistance make it ideal for durable and aesthetic designs.
What role does PMMA play in the electrical industry?
In the electrical industry, PMMA is used for housings and covers that require high transparency and electrical insulation at the same time. It is also used in LED lenses and luminaires as it conducts light efficiently.
How sustainable is PMMA and can it be recycled?
PMMA is recyclable to a certain extent. Through thermal recycling, it can be broken down into monomers and used to produce new PMMA. This process reduces waste and promotes the circular economy, especially in the advertising industry where PMMA is used for signs and displays.
What advantages does PMMA offer compared to glass?
PMMA is more shatterproof, lighter and easier to process than glass. It offers a similarly high level of transparency and is therefore an ideal alternative for applications where weight or safety play a role.
