Polymer Type |
| Thermoplastic |
Advantages |
| Higher tensile strength, flexural modulus, dimensional stability and heat distortion temperature than unmodified PA 6/10. |
Disadvantages |
| Very low elongation at break and reduced notched izod impact strength compared with unmodified PA 6/10. Mechanical properties of mouldings can be anisotropic. |
