Polymer Type |
Thermoplastic |
Advantages |
Good tensile strength, flexural modulus, dimensional stability, friction and wear properties compared with unmodified polyamide 6/6 plastics. High values of thermal and electrical conductivity (could relate to a disadvantage). |
Disadvantages |
Mouldings may have anisotropic properties. Poor electrical resistance with significant reduction in elongation at break. Are expensive compared with unmodified polyamide 6/6 plastics. |
