PA12 (Polyamide 12, or Nylon 12) is a long-chain semi-crystalline engineering thermoplastic. It is highly valued for having the lowest water absorption among common nylons, which gives it excellent dimensional stability and makes it ideal for precision components.
Core Properties of PA12
- Lowest Water Absorption: Compared to PA6 and PA66, PA12 absorbs very little moisture, meaning parts maintain their exact dimensions even in humid environments.
- Chemical Resistance: Excellent resistance to fuels, hydraulic fluids, and various industrial chemicals.
- Low-Temperature Toughness: Maintains good impact resistance even at sub-zero temperatures.
- Lightweight: Often used as a lightweight replacement for metal tubing.
Typical Applications
Because of its low moisture absorption and high stability, PA12 is widely used in:
- Automotive: Fuel lines, pneumatic brake lines, and cable jacketing.
- Medical: Precise medical tubing and catheter components.
- Electronics: Precision connectors and wire insulation.
