Nylon and polycarbonate are two of the most specified engineering thermoplastics. Both offer excellent mechanical properties, but their unique characteristics—impact resistance for polycarbonate, wear resistance for nylon—make each better suited for specific applications.
Mechanical Properties Compared
| 속성 | Nylon (PA6) | 폴리카보네이트(PC) |
|---|---|---|
| 인장 강도(MPa) | 70-85 | 55-75 |
| 굴곡 탄성률(GPa) | 2.5-3.0 | 2.2-2.4 |
| Notched Izod Impact (kJ/m²) | 5-15 | 60-80 |
| 밀도(g/cm³) | 1.14 | 1.20 |
Impact Resistance: Polycarbonate’s Signature Strength
Polycarbonate is legendary for its impact resistance—it’s used in bulletproof glass and safety goggles. With notched Izod impact values of 60-80 kJ/m², PC is virtually unbreakable under normal use.
Thermal and Optical Properties
Polycarbonate is naturally transparent with light transmission of 88-90%. Nylon is naturally translucent to opaque.
내화학성
Nylon holds a distinct advantage here. Polycarbonate has poor chemical resistance—it’s attacked by hydrocarbons, ketones, and many cleaners. Nylon offers excellent resistance to oils, greases, fuels, and many organic solvents.
Moisture and Environmental Resistance
Polycarbonate absorbs negligible moisture (0.15-0.35%). Nylon’s moisture absorption (2.5-3.0%) can cause dimensional changes. However, PC is susceptible to UV degradation.
Application Guide
Choose Nylon When:
- Chemical resistance to oils and fuels is needed
- Wear resistance matters
- Parts must survive dynamic loading
Choose Polycarbonate When:
- Optical clarity is required
- Exceptional impact resistance is critical
- Dimensional stability under varying humidity is needed
