PMMA: The Clear Plastic with Many Uses
At PlastShop.se, we offer a wide range of plastic materials. Today, we're taking a closer look at PMMA, also known as poly(methyl methacrylate). It's a plastic with outstanding optical properties and many applications.
Incredible Transparency
One of the most prominent features of PMMA is its high transparency. With a light transmission of 92%, it's 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 signs.
UV Resistance and Weather Resistance
PMMA isn't just transparent; it's also highly resistant to UV radiation and weathering. This means you can use it 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.
How does PMMA differ from other materials like PC and PETG?
PMMA Compared to PC and PETG
PC (polycarbonate) is also a common material with high optical clarity, but it's not as UV-resistant as PMMA. PETG (polyethylene terephthalate glycol) is a more flexible material that's easier to process, but it doesn't have the same high transparency as PMMA.
Processing PMMA
When processing PMMA, it's important to be aware that the material can be sensitive to heat. Therefore, we must use appropriate tools and techniques to avoid damage. It's also important that the material is clean and dry before processing.
Common Applications
Typical applications for PMMA include displays, signs, lighting, and aquariums. It's also used in medical technology and the automotive industry. The material has a Shore hardness of 65° Shore D.

When using PMMA, it's good to remember that the material can be relatively brittle and sensitive 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, don't hesitate to contact us. We're happy to help you choose the right material!
