PMMA, polycarbonate or PET-G — and ACM or HPL?
For transparent work: PMMA (acrylic) is the clearest and polishes best, polycarbonate is virtually unbreakable but scratches sooner, PET-G sits in between and forms well. For sheet material: ACM is light and flat and the standard for facade signage; HPL is hard and wear-resistant and suits interiors and visible parts. The choice follows from application, indoor or outdoor use, impact resistance and finish. Unsure? Milplex advises based on your application — reply within 1 business day.

For panels: ACM is light and weatherproof (façade/signage), HPL is robust and decorative (interiors/counters). Unsure? Send your request — we advise based on the application.
Transparent plastics: PMMA vs polycarbonate vs PET-G
| Property | PMMA (acrylic) | Polycarbonate (PC) | PET-G |
|---|---|---|---|
| Clarity | Very clear, glass-like | Clear | Clear |
| Impact resistance | Moderate | Very high (near unbreakable) | High |
| Scratch resistance | Good | Moderate | Moderate |
| Thermoforming/bending | Good (hot bending) | Good | Very good |
| UV/weather resistance | Very good | Good (may yellow) | Moderate |
| Laser cutting | Excellent (clean edge) | Difficult (discolours) | Good |
| Typical use | Displays, visible work, signage | Protective screens, machine guards | Vacuum forming, food-safe, displays |
Panels: ACM vs HPL
| Property | ACM (Alubond/Dibond) | HPL |
|---|---|---|
| Build-up | Aluminium–plastic–aluminium sandwich | Pressed paper/resin laminate |
| Weight | Light | Heavier |
| Outdoor/façade | Excellent | Limited (compact HPL works) |
| Processing | Milling, rout-and-fold | Milling, sawing |
| Finish/appearance | Evenly sprayed colours | Decor, wood-look, many colours |
| Typical use | Façade signage, signage, panels | Interiors, counters, furniture, visible work |

Frequently asked questions
Which material is strongest against impact?
Polycarbonate is near unbreakable; PET-G is a good alternative. PMMA (acrylic) is clearer but more brittle.
Which material for outdoor or façade use?
ACM (Alubond) is light and weatherproof, ideal for façade and signage. PMMA is UV-resistant for visible work.
What is best for clean interior visible work?
PMMA/acrylic for clear displays; HPL for robust, decorative interior panels and counters.
