Polymer Type |
| Thermoplastic |
Advantages |
| Improved notched impact strength and abrasion resistance, softer and more flexible than unmodified PA 11. |
Disadvantages |
| Higher coefficient of expansion, reduced heat distortion temperature and resistance to creep compared with unmodified PA 11. |
