What are the machining challenges of PMMA?

PMMA is brittle compared to PC, so careful machining is needed to avoid cracking.

Is PMMA weather-resistant?

PMMA has excellent UV and weather resistance, making it suitable for outdoor applications.

Can PMMA achieve a glass-like finish?

Yes. PMMA can be polished to achieve high transparency and smoothness.

What industries use PMMA parts?

Display, lighting, medical, and automotive i ndustries frequently use PMMA for covers and optical components.

How does PMMA compare to PC?

PMMA is lighter and more transparent but less impact-resistant than PC, making it cost effective for non-structural optical uses.
