Polymer Type |
| Thermoplastic |
Advantages |
| Better tensile strength, flexural modulus, heat distortion temperature and dimensional stability than unmodified PA 6/6. |
Disadvantages |
| Lower elongation at break and notched izod impact strength than unmodified PA 6/6. Incorporation of glass fibres can cause anisotropy in mouldings. |
