This semi-crystalline thermoplastic is one of the most widely used engineering thermoplastics with well-balanced properties in strength, stiffness and chemical resistance. It has improved surface appearance and processability compared to PA 66 but lower modulus and absorbs moisture more rapidly. PA 6 can be processed by extrusion (e.g. fibres, profiles) and injection. PA 6 also has good resistance to fatigue.
Applications:
- Gears
- Cams
- Power housings
- Rollers
- Bearing
- Electrical connectors
- Nuts and bolts
- Automotive fuel tanks.
Polyamide 66 (PA 66)
PA 6.6 offers an excellent balance of mechanical properties (strength, stiffness, impact) and heat / chemical resistance. Therefore, PA 6.6 very often is considered as an outstanding candidate for metal replacement. It is resistant to heat, which can be advantageous for retention of torsion.
Applications:
- Gears
- Cams
- Power housings
- Rollers
- Bearing
- Electrical connectors
- Nuts and Bolts
- Automotive fuel tanks
