Polymer Type |
| Thermoplastic |
Advantages |
| Low coefficient of friction, slightly better heat distortion temperature and oxygen index compared with unmodified polysulphone. |
Disadvantages |
| Lower tensile strength, elongation at break and notched izod impact strength compared with unmodified polysulphone. |
