主要特点
| 特点 | 重要性 |
|---|---|
| Excellent transparency (≈ 88 % light transmittance, 3 mm) | Shows internal features, pigments cleanly; rivals PMMA while staying tougher. |
| Medium–high flow – MFR ~ 12 g/10 min (220 °C / 10 kg) | Fills thin-wall, multi-cavity tools without knit-line haze. |
| Tough & ductile – Notched Izod ≈ 200 J/m (23 °C) | Resists drop impact better than PMMA and SAN blends. |
| Good chemical gloss retention | MMA matrix slows stress-cracking from alcohol-based lotions and household cleaners. |
| Easy colouring / metallising | Clear base accepts dyes, pearl masterbatch or vacuum-plating without primer. |
(Values are nominal; always verify with the current LG Chem TDS for your lot.)
