Polymer Type |
| Thermoplastic |
Advantages |
| Superior impact properties and very low notch sensitivity compared with other engineering thermoplastics. Short moulding cycles therefore higher productivity. Good chemical resistance. Good surface finish. |
Disadvantages |
| Low flexural modulus and maximum operating temperature when compared with unmodified PA 6/6. |
