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.
