Advantages |
| Significantly higher flexural modulus and notched impact strength, improved tensile strength, HDT and mould shrinkage compared with unmodified polyimide. |
Disadvantages |
| Reduced elongation at break, oxygen index and electrical characteristics compared with unmodified polyimide. |
