NDA VACU

Test set NDA VACU for the analysis of sieve residue

Mechanical flushing method – Functional principle according to ASTM D 7724

This test method covers the determination of non-dispersible matter after mechanical water flushing of carbon blacks (and other powder materials).

The process provides information of the content of coarse impurities or constituents which are insoluble in water, such as ceramic constituents, metals or heavily compacted pigments.

The principle and the related test method have been developed to determine the non-dispersible matter on a specific class of carbon blacks called Mechanical Rubber Grades (MRG).

It delivers reproducible results even with the most difficult products.
