Polyamide is a semi-crystalline engineering plastic. Its stiffness, strength, wear resistance, and good friction properties make polyamide a popular material in machine design. The common weakness of PA is its tendency to absorb water – this influences the mechanical properties and dimensional accuracy of components.
There are several different types of polyamides, with slightly differing characteristics. The Plasticprop sample represents the very common PA 6. The polyamide family also includes an amorphous grade, the transparent PA 12.
PA12 is similar to PA6 and PA66 but has some improved properties.
Why choose (over PA6 or PA66)?
- Absorbs less moisture, better dimensional stability
- Better impact properties
- Excellent resistance against stress-cracking
- Better wear resistance
- Good weather resistance
- Better durability against aging
- Excellent colorability
- Easier to process
Why not choose?
- Tensile modulus is lower than those of PA6 and PA66
- Expensive material (The long list of advantages does not come for free)
- Motorcycle parts
- Bike pedals
- Housings for high-quality electronic devices
