Nylon isn’t one material—it’s a family of polyamides with distinctly different properties. From the workhorse PA6 to the premium PA12, understanding the full range of nylon grades helps you select the optimal material for your application.
The Nylon Family Overview
| 등급 | 유형 | 녹는점 | Moisture (50% RH) | Key Characteristic |
|---|---|---|---|---|
| PA6 | Aliphatic | 220°C | 2.7% | Toughness, processability |
| PA66 | Aliphatic | 260°C | 2.5% | Strength, heat resistance |
| PA11 | Bio-based | 185°C | 0.8% | Flexibility, low moisture |
| PA12 | Aliphatic | 178°C | 0.7% | Lowest moisture absorption |
| PA46 | Aliphatic | 295°C | 3.5% | Highest heat resistance |
PA6: The Versatile Workhorse
PA6 is the most widely used nylon grade, representing approximately 60% of nylon consumption. It offers an excellent balance of strength, toughness, and processability.
주요 속성
- Tensile strength: 70-85 MPa
- Excellent impact resistance
- Good surface finish and colorability
- Wider processing window than PA66
PA66: The High-Performance Standard
PA66 offers approximately 10-15% higher strength and stiffness than PA6, with superior heat resistance. It’s the preferred choice for demanding applications.
PA11 and PA12: The Specialty Nylons
PA11 and PA12 are distinguished by their exceptionally low moisture absorption—less than 1% even at saturation. This gives them outstanding dimensional stability.
PA46: The High-Temperature Specialist
PA46 (Stanyl) offers the highest heat resistance of any aliphatic nylon, with a melting point of 295°C.
Selection Guide
