Polymer Type |
| Thermoplastic |
Advantages |
| Good balance of rigidity, strength and dimensional stability. Resistance to discolouration on heating. Excellent thermal and chemical resistance. |
Disadvantages |
| Harmful odours can be evolved during processing. Adequate ventilation should be provided. Granules must be thoroughly dried before processing to limit the occurrence of hydrolytic degradation. High mould temperatures ( 140°-160°C / 285°-320°F ) required for optimum properties. |
