| ITEM | PMMA (Acrylic) | PC (Polycarbonate) |
| Proportion | 1.19 | 1.2 |
| Impact resistance | Fragile | 30 times stronger than acrylic |
| Transmittance | 92% | 88% |
| Processing temperature | Under 80°C | Under 120°C |
| Water absorption | 0.3~0.4% | 0.1~0.2% |
| Under prolonged UV light exposure | Not easy to yellow |
easy to yellow, Need to add UV absorber layer |
| Flame retardant degree | Low (UL 94 level HB) | High (UL 94 level V0) |
| Selling cost | Ordinary | More Expensive |
Q: What are the advantages of acrylic PMMA?
Transmittance(ASTM D1003)
Rockwell hardness (ASTM D785)
Heat distortion temperature (ASTM
D648)
Bending strength (ASTM
