Polymer Type |
| Thermoplastic |
Advantages |
| Higher heat distortion temperature than conventional grades of ABS by approx. 15°C ( 25°F ) at 0.45Mpa ( 66psi ). |
Disadvantages |
| Requires higher mould surface temperatures and higher temperature profiles in processing than typical grades of ABS. Hence moulding cycle times are likely to be longer. |
