Polycarbonate is excellent impact resistance but is low surface hardness, so it improves its tolerance with the improvement of surface hardness as double-layer processing of PMMA materials in one surface.
|
|
 |
 |
1. It is excellent of impact hardness and impact scratchness.
2. It is excellent of thermal resistance and light transmittance.
