PMMA Arkema DR101 (France)
PMMA Arkema DR101 is impact‑modified polymethyl methacrylate. It features good dimensional stability, excellent chemical resistance, moderate heat‑resistance and balanced optical performance.
Main Applications
Safety protection: riot‑proof shields, inner layer for bullet‑proof glazing (high‑impact property).
Automotive industry: taillight housings, signal lamps, instrument panel covers, interior structural parts, requiring weather‑resistance and optical performance.
Electronics & optics: mobile‑phone panels, instrument housings, light guides, optical lenses, electrical appliance components.
Medical & packaging: medical‑device observation windows (potential ISO 10993 compliance), drug containers, food‑contact containers.
Building & household: bathroom articles, outdoor advertising films, architectural glazing, lamp housings, diffusers.
Consumer goods: home‑appliance parts, stationery.

Injection‑Molding Parameters
| Process | Item | Recommendation | Notes |
|---|---|---|---|
| Predrying | Drying temperature | 80‑85 ℃ | Desiccant dryer required |
| Drying time | 2.0‑5.0 h | Suggest 4‑5 h; moisture＜0.1% to avoid bubbles & silver‑streaks | |
| Barrel setting | Rear zone | 185‑205 ℃ | Process window: 160 ℃ flow onset, decompose＞270 ℃ |
| Middle zone | 220‑240 ℃ | Control residence time to prevent degradation | |
| Front zone | 210‑230 ℃ | ||
| Nozzle temperature | 210‑230 ℃ | ||
| Melt temperature | 210‑250 ℃ | ||
| Mold temperature | 70‑80 ℃ | Higher temp improves gloss & reduces internal stress, longer cycle | |
| Injection pressure | Adjust per product & mold | Use lowest feasible pressure for full filling & good appearance | |
| Injection speed | Medium | Higher speed allowed for thin‑wall complex parts; avoid over‑speed defects | |
| Back pressure | 0.5‑1.0 MPa | Low back‑pressure for melt homogenization | |
| Screw suggestion | — | L/D 18:1‑24:1, compression ratio 2:1‑3:1; floating seal ring preferred |
