90 % of material is < 361.884 - Executive summary:
Both visual microscope and laser diffraction test were conducted to determine the particle size analysis of Nadide powder. The study was conducted in accordance with ISO 13320:2009. For the full solubility and dispersability test, silicone oil was selected. The sample proved to be insoluble and well dispersed in silicone oil, therefore it was chosen as the suspension fluid.
The particle size was analysed over the range 0.02 Um to 2000 Um. The Mass Median Aerodynamic Diameter (MMAD) was 172.799 Um.
