Optical PMMA Acrylic & Polycarbonate PC Precision Machining

92% Light Transmittance, 250x Impact Resistance of Glass & Vapor Polishing.

PMMA (Acrylic / Plexiglass) and Polycarbonate (PC / Lexan) are the two indispensable clear engineering plastics. PMMA provides supreme optical clarity (92% light transmission, exceeding glass), superior UV resistance, and accepts diamond vapor polishing to total transparency. Polycarbonate offers virtually unbreakable impact strength (250 times stronger than glass), making it ideal for bulletproof sight glasses, aerospace canopies, and autoclave medical manifolds.

Frequently Asked Questions

Common engineering questions regarding tolerances, material traceability, and turnaround for Optical PMMA Acrylic & Polycarbonate PC Precision Machining.

What is the key difference between Acrylic (PMMA) and Polycarbonate (PC)? +
Acrylic has higher optical clarity (92% vs 89%), resists scratching better, and polishes to a crystal shine. Polycarbonate is virtually unbreakable with 250x the impact strength of glass.
How does vapor polishing work? +
The part is briefly exposed to heated solvent vapor. The vapor condenses on the surface, melting micro-ridges left by cutting tools, and evaporates within seconds to leave a glass-smooth surface.
Will machined acrylic crack when exposed to alcohol? +
Machined acrylic has residual stress. Exposure to alcohol or solvents can cause immediate stress crazing unless the part is properly oven-annealed before chemical contact.
Can you machine microfluidic channels in PMMA? +
Yes. We routinely mill micro-channels down to 50 microns wide by 50 microns deep with sharp bottom corners for medical lab-on-a-chip diagnostic devices.
