CNC Machining for Polycarbonate Parts
Machined polycarbonate offers excellent dimensional stability and mechanical properties
Polycarbonate (PC) is an engineering plastic with excellent dimensional stability and good strength and stiffness. It's a go-to material for parts that need clarity and impact strength.
We offer four grades of machined polycarbonate:
- Black
- Clear
- Translucent
- 20% Glass-Filled

Machined Polycarbonate Properties
| Tensile Strength at Yield | Flexural Modulus | Tensile Elongation at Break | |
|---|---|---|---|
| Test Method | ASTM D638 | ASTM D790 | ASTM D638 |
| Translucent | 8,000 psi | 340,000 | 50% |
| Clear | 8,990 psi | 338,000 | 140% |
| 20% Glass-Filled | 16,000 | 796,000 | 5% |
