What is Acrylic (PMMA)?
Acrylic (PMMA) is a high-performance thermoplastic widely used in CNC machining for its excellent clarity, lightweight nature, and durability.
Compared to glass, acrylic offers superior impact resistance while maintaining outstanding optical transparency, making it ideal for precision components and visual applications.
It is commonly used for display panels, lighting components, protective covers, and custom-engineered parts requiring both aesthetics and performance.
Acrylic (PMMA) CNC Machining Applications
Thanks to its excellent optical clarity (up to 92% light transmission), impact resistance, and ease of precision machining, Acrylic (PMMA) is widely used across multiple industries. CNCTAL delivers high-quality custom acrylic parts for both prototyping and low-volume production.
