Polymer Type |
| Thermoplastic |
Advantages |
| Good tensile strength, creep resistance and heat distortion temperature combined with low mould shrinkage and good dimensional stability compared with unmodified PA 11. |
Disadvantages |
| Low elongation at break and poor resistance to abrasion compared with unmodified PA 11. More difficult to process than glass bead filled grades due to high melt viscosity. Mechanical properties can be highly anisotropic. |
