Polymer Type |
| Thermoplastic |
Advantages |
| Very flexible, good abrasion resistance, good-notched izod impact strength and better elongation at break compared with unmodified polyamide 12. |
Disadvantages |
| Reduced heat distortion temperature, increased coefficient of linear expansion and poor electrical characteristics compared with unmodified polyamide 12. |
