PA66 (Polyamide 66, or Nylon 66) is a semi-crystalline engineering thermoplastic known for its high mechanical strength, rigidity, and excellent heat resistance. It is one of the most widely used polyamides in automotive and electronic applications.
Core Properties of PA66
- High Heat Resistance: Melting point is 250°C - 260°C, significantly higher than PA6, allowing it to withstand higher continuous service temperatures.
- Mechanical Strength: PA66 has higher tensile strength and better creep resistance under continuous load compared to PA6.
- Wear Resistance: Excellent sliding properties, often used for high-load gears and bearings.
- Water Absorption: While still hygroscopic, PA66 absorbs less moisture than PA6, resulting in better dimensional stability for precision parts.
Common PA66 Forms & Grades
We supply PA66 in multiple forms to suit different manufacturing processes:
- PA66 Granules: Virgin resin for injection molding and extrusion.
- PA66 Rod & Sheet: Extruded stock shapes for CNC machining into insulators, wear pads, and structural parts.
- Modified PA66: We supply custom compounded grades including Glass-Fiber Reinforced (GF30) (usually black), Flame Retardant (V0), and impact-modified versions.
Typical Applications
Because of its high strength-to-weight ratio, PA66 is widely used in:
- Automotive: Under-the-hood components, radiator tanks, and electrical connectors.
- Electronics: Circuit board standoffs, terminal blocks, and coil bobbins.
- Industrial Machinery: High-load gears, rollers, and wear pads.
