| Installing 2mm outdoors | UV fade + wind damage | Use 3mm UV-protected |
| Skipping edge support | Sagging over time | Add aluminum trim |
🔬 Laboratory Test Results
(ASTM Standards | 2-Year Simulated Wear)
| Thickness | Scratch Resistance | Water Swell | Load Capacity |
|---|---|---|---|
| 1mm | Scratched @ 1N force | 0.3% swell | 15 PSI |
| 2mm | Resists @ 3N | 0.08% swell | 45 PSI |
| 3mm | Resists @ 5N | 0.02% swell | 120 PSI |
| 5mm | Resists @ 8N | 0.01% swell | 300 PSI |
🏠 Application-Specific Recommendations
| Project Type | Ideal Thickness | Pro Tip |
|---|---|---|
| Shower Walls | 3mm HydroShield™ | Use silicone-sealed edges |
| Kitchen Backsplash | 2-3mm | Keep 6″ from stove |
| Retail Flooring | 5mm DiamondGrip™ | Add wear layer |
| Office Partitions | 2mm LightWeight™ | Frame with aluminum |
| Furniture Tops | 4mm ScratchArmor™ | Round sharp corners |
