Test Results
Residual moisture
The test item was dried in a Sartorius infrared moisture analyzer at 120 °C until constant weight. The residual moisture was 0.1 wt.-%.
Particle size distribution
The separation of coarse grain was not necessary for the determination of the particle size.
The test item showed a poly-modal particle size distribution with a median particle size of D50 = 185 μm, Figure 1. A first small maximum is found at approx. 6 μm, a second at approx. 30 μm and the main peak at approx. 200 μm.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
