Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The particle size distribution of samples of trimellitic anhydride flakes and drops, typical of the commercial production, was characterised by a sieving method. As result, 95% of particles are larger than 400 microns and less than 1% are smaller than 50 microns.

Additional information

The data provided by this particle size analysis are compatible with independently collated data contributed by members of the Trimellitic Anhydride Sub-Group of the Polyester Monomers Consortium (contributors anonymised, number of sources not known), whose collective particle size distribution data are described by the following envelope: 95% larger than 400 microns and less than 1% are smaller than 50 microns.
