PMMA: The clear plastic with many uses
At PlastShop.se, we offer a wide range of plastic materials. Today, we’re going to take a closer look at PMMA, also known as poly(methyl methacrylate). It is a plastic with outstanding optical properties and a wide range of applications.
Incredible transparency
One of the most notable properties of PMMA is its high transparency. With a light transmission of 92%, it is among the most transparent plastic materials available. This makes it an excellent choice for applications where light transmission and clarity are crucial, such as displays and signage.
UV resistance and weather resistance
PMMA is not only transparent, but also highly resistant to UV radiation and weathering. This means it can be used outdoors without losing its clarity or strength, even in environments with strong sunlight. This makes it suitable for outdoor advertising, lighting and other applications where the material is exposed to the elements.
So how does PMMA differ from other materials such as PC and PETG?
PMMA compared with PC and PETG
PC (polycarbonate) is also a common material with high optical clarity, but it is not as UV-resistant as PMMA. PETG (polyethylene terephthalate glycol) is a more flexible material that is easier to process, but it does not have the same high transparency as PMMA.
Processing PMMA
When machining PMMA, it is important to be aware that the material can be sensitive to heat. We must therefore use suitable tools and techniques to avoid damage. It is also important that the material is clean and dry before machining.
Common applications
Typical applications for PMMA include displays, signage, lighting and aquariums. It is also used in medical technology and the automotive industry.

When using PMMA, it is worth bearing in mind that the material can be relatively brittle and susceptible to scratches. Handle it with care and avoid unnecessary stress.
We hope this information has given you a better understanding of PMMA and its applications. If you’re considering using PMMA in your next project, please don’t hesitate to contact us. We’d be happy to help you choose the right material!
