Material comparison
Acrylic (PMMA) vs Polycarbonate (PC)
Both are clear glazing plastics. Acrylic is clearer, harder and more scratch- and UV-resistant, and lower cost; polycarbonate is far more impact-resistant but softer and pricier.
Acrylic (PMMA) vs Polycarbonate (PC) — side by side
| Acrylic (PMMA) | Polycarbonate (PC) | |
|---|---|---|
| Clarity | Highest | High |
| Impact resistance | Moderate (brittle) | Very high |
| Scratch resistance | High | Low (needs hard-coat) |
| UV / weather | Excellent | Good (coated) |
| Cost | Lower | Higher |
| Typical use | Signage, lighting, glazing, displays | Guards, security glazing, high-impact covers |
Choose Acrylic (PMMA) when…
- Optical clarity, gloss and scratch resistance
- Signage, lighting diffusers, skylights, displays
- Outdoor clarity at lower cost
Choose Polycarbonate (PC) when…
- High impact or safety-critical glazing
- Machine guards and security screens
- Parts that must not shatter
The verdict: Choose acrylic for clarity, gloss, scratch and UV at lower cost; choose polycarbonate where impact or safety is the priority. Acrylic is harder and clearer, PC is tougher.
