PC Material Properties
PC (Polycarbonate) is a high-performance thermoplastic known for its exceptional impact resistance, optical clarity, and heat stability. Its unique molecular structure allows it to be lightweight yet highly durable, making it ideal for demanding applications. Key Material Properties:
- High impact resistance – withstands significant mechanical stress
- Superior optical clarity – excellent for transparent and translucent components
- Good dimensional stability – maintains precision in high-temperature environments
- Flame retardant – commonly used in electronics and safety equipment
| Property | Density | Tensile Strength | Flexural Strength | Impact Strength (Unnotched) | Heat Deflection Temp (0.45 MPa) |
|---|---|---|---|---|---|
| Value/Description | 1.18 - 1.22g/cm³ | 55 - 75 MPa | 80 -110 MPa | 60 - 80 kJ/m² | 125 - 135℃ |
- The above parameters represent the baseline performance of the materials. Actual application should be dynamically optimized based on specific working conditions.
