Conclusions:
The product is manufactured as flakes. Nearly 70% per weight of the product are particles with diameters between 2.0 mm and 5.6 mm. Only 0.28% of the particles have diameters below 0.045 mm.
Executive summary:

The product is manufactured as flakes. Nearly 70% per weight of the product are particles with diameters between 2.0 mm and 5.6 mm. Only 0.28% of the particles have diameters below 0.045 mm.

This study was taken as "key study" as its results are representative for the substance in the quality in which it is actually placed on the market.

Description of key information

Less than 0.28% of the mass of the test item have a diameter below 100 µm.
