Polymer Type |
| Thermoplastic |
Advantages |
| Excellent abrasion resistance, better notched izod impact strength, lower tensile modulus, softer and more flexible than unmodified PA 11. |
Disadvantages |
| Reduced heat distortion temperature, creep resistance and higher coefficient of linear expansion than unmodified PA 11. Poor retention of physical properties at temperatures above 95°C due to plasticiser loss. |
