Advantages |
| Very good fire retardant characteristics compared with non fire- retarded grades of DAP. Good tensile strength, notched impact strength, heat distortion temperature and mould shrinkage compared with other modified grades of DAP. |
Disadvantages |
| Most expensive and highest density compared with other filled grades of DAP. |
