Additional information

The particle size distribution of DCDPS powder was determined similar to OECD TGD 110 and ISO 13320-1 methods under non-GLP conditions (N.N. BASF 2009c). About 7.5% of DCDPS belongs to inhalable fraction. No respirable fraction was identified.

The dustiness of the powder is classified as “medium” due to the particle size distribution (D10=115 µm, D50=240 µm, D90=561 µm). The dustiness of the pellets is classified as “low” because the pellets are not dusty.
