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
| プロパティ | Nylon (PA6) | ポリカーボネート（PC） |
|---|---|---|
| 引張強さ (MPa) | 70-85 | 55-75 |
| 曲げ弾性率 (GPa) | 2.5-3.0 | 2.2-2.4 |
| Notched Izod Impact (kJ/m²) | 5-15 | 60-80 |
| 密度 (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.
耐薬品性
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
いつナイロンを選ぶか：
- 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

よくあるご質問
How do you know whether Nylon vs Polycarbonate: Strength, Heat Resistance, and Cost Compared fits a part?
Nylon vs Polycarbonate: Strength, Heat Resistance, and Cost Compared fits a part when its load capacity, temperature range, moisture exposure, wear behavior, and processing method match the real service conditions.
What properties should be checked for Nylon vs Polycarbonate: Strength, Heat Resistance, and Cost Compared?
Check strength, stiffness, impact resistance, heat resistance, moisture absorption, dimensional stability, friction, wear, and chemical compatibility.
What is the biggest selection risk for Nylon vs Polycarbonate: Strength, Heat Resistance, and Cost Compared?
The biggest risk is choosing from a datasheet value without considering actual environment, processing method, part geometry, and long-term use.
When should Nylon vs Polycarbonate: Strength, Heat Resistance, and Cost Compared be tested before production?
Testing is recommended when the part faces load, heat, chemicals, moisture, tight tolerances, regulatory requirements, or a new operating environment.
