| Property Category | Polycarbonate (PC) | PMMA (Acrylic) |
| Transparency | 85–90% light transmittance; slightly yellowish under long-term UV exposure | 92–93% light transmittance (higher than glass); crystal-clear optical effect |
| Impact Resistance | Excellent (200–300 times that of PMMA); unbreakable under normal impact | Poor; brittle and prone to cracking under impact |
| Heat Resistance | High heat deflection temperature (HDT: 120–135°C); can withstand short-term high temperatures | Low HDT (80–100°C); deforms easily under high temperatures |
| UV Resistance | Can be modified with UV stabilizers for outdoor use (3–5 years of weather resistance) | Natural PMMA has poor UV resistance; surface coating required for outdoor applications |
| Machinability | Good for injection molding and CNC machining; low warpage rate | Excellent for precision machining and polishing; easy to achieve mirror finish |
| Customization Advantages | Suitable for structural parts requiring both transparency and impact resistance | Ideal for optical components and decorative parts requiring ultra-high transparency |
