PA46 Nylon: High Heat Resistance & Rigidity

Understanding the high-temperature performance of Nylon 46.

PA46 (Polyamide 46, or Nylon 46) is a high-temperature aliphatic polyamide known for its outstanding heat resistance and high crystallinity. Unlike standard nylons, PA46 maintains excellent mechanical properties even at elevated temperatures.

Core Properties of PA46

  • High Melting Point: With a melting point of approximately 295°C, PA46 can withstand higher continuous service temperatures compared to PA6 or PA66.
  • High Crystallinity: This results in high stiffness, excellent creep resistance, and rapid crystallization during processing.
  • Fatigue Resistance: PA46 is highly resistant to repeated mechanical stress, making it ideal for moving parts.

Typical Applications

Because of its high heat resistance and mechanical strength, PA46 is widely used in:

  • Automotive: Under-the-hood components exposed to high temperatures, such as air intake manifolds and engine covers.
  • Electronics: SMT (Surface Mount Technology) components and connectors that require high heat resistance during soldering.
  • Industrial: Gears, bearings, and high-load structural parts.
