Advantages |
| Best tensile strength, flexural modulus, notched impact strength and heat distortion temperature compared with other modified grades of DAP. |
Disadvantages |
| As with other glass filled DAP mouldings, can be anisotropic with a tendency to warp. Expensive compared with other filled grades of DAP. |
