PMMA (Acrylic) Material List


Basic Knowledge of PMMA (Acrylic)

What is PMMA (Acrylic)?

PMMA, or acrylic, is a clear and durable plastic often used for outdoor applications due to its UV resistance and weatherability. It's commonly chosen for transparent needs like signage and displays, as well as for wear-resistant purposes in automotive parts. It is a cost-effective alternative to glass, being significantly cheaper. Although not as hard as glass, PMMA is more impact-resistant and less prone to shattering.

Additionally, it is lighter than glass, so it is easier to handle and install. PMMA is resistant to many chemicals, although certain solvents can cause it to craze or crack. The purity of the raw material influences whether the plate will bend, deform, or shrink and whether the surface will be chapped during processing. It's a popular material for CNC machining due to its ease of work, toughness, and precise machinability.

Machining PMMA (Acrylic) Buying FAQ

Please describe your requirements in detail (material, quantity, process, etc.) and attach 2D/3D drawings via the online form or send an email directly to, and you will receive our reply within 6 hours.
Yes, we understand the importance of prototypes to you, so we will sign a confidentiality agreement and fully comply with it.
Our custom acrylic costs depend on the quantity of your project, the complexity of the processing, and the surface treatment process. You can send us your project requirements through our online quotation or email to evaluate the price.
PMMA, or polymethyl methacrylate, is not inherently scratch-resistant. While it has good optical clarity and can be polished to a high shine, it is relatively softer than other materials. To enhance scratch resistance, surface treatments or coatings can be applied.
PMMA is not commonly used in 3D printing due to its high melting temperature and tendency to warp during the printing process. However, some advanced 3D printing technologies, like high-temperature printers, can handle PMMA.
Exposure to low temperatures makes it more prone to brittleness, and prolonged sunlight exposure can cause degradation, further increasing its brittleness. Additionally, sharp corners or notches act as stress concentrators, contributing to the material's overall brittleness.
PMMA is not soluble in water. It is relatively inert to water, which makes it suitable for applications where water resistance is essential. However, it can be dissolved in some organic solvents like acetone and chloroform.
