Description of key information
0.35 mm > D50 > 1.19 mm
Additional information
The particle size distribution was determined by sieve analysis according to national Brazil guideline 84/96 -IBAMA.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
