Understanding the Nylon Family
Polyamide (nylon) materials differ in molecular structure, affecting properties and applications.
PA6 — Polyamide 6
- Melting Point: 220°C
- Advantages: Better impact resistance, lower cost, easier processing
- Best for: General mechanical parts, 3D printing, consumer products
PA66 — Polyamide 66
- Melting Point: 265°C
- Advantages: Higher heat resistance, superior mechanical strength
- Best for: Automotive engine parts, high-temperature applications
PA12 — Polyamide 12
- Melting Point: 180°C
- Advantages: Lowest moisture absorption, best chemical resistance
- Best for: Fuel lines, outdoor applications, moisture-sensitive environments
Selection Guide
Choose PA66 for heat, PA6 for cost/impact, PA12 for moisture/chemical resistance.
