Polymer Type |
| Thermoplastic |
Advantages |
| Higher tensile strength, flexural modulus, and heat distortion temperature accompanied by lower mould shrinkage than unmodified amorphous (transparent) Polyamide. |
Disadvantages |
| Mechanical properties of mouldings may be anisotropic. Low elongation at break and notched izod impact strength compared to unmodified amorphous (transparent) Polyamide. |
