How to Measure Compaction Force, Compactability and Compressibility
COMPACTABILITY/COMPRESSIBILITY is the ability to be compacted or compressed usually to a large degree of deformation during a compression test. This can be a required property of, for example, the formation of cosmetic powder tablets or formation of tablets from granules. However it may also be undesirable, as would be true of a large amount of packaging material which is usually chosen for its ability to protect a product and therefore resist compaction to a reasonable extent.
Typical properties that can be obtained from a texture analyser graph:
Work of Compaction, Force to Compact, Ease of Compression, Point of Non-Recoverable Failure, Compression Recovery
Typical Texture Analyser graph with annotated properties of powder compaction test
Typical Probe/Fixture used for Measurement:
Cylinder Probes of all sizes >>
The above are only typical examples of compactability/compressibility measurement. We can, of course, design and manufacture probes or fixtures that are bespoke to your sample and its specific measurement.
Once your measurement is performed, our expertise in its graphical interpretation is unparalleled – no-one understands texture analysis like we do. Not only can we develop the most suitable and accurate method for the testing of your sample, but we can prepare analysis procedures that obtain the desired parameters from your curve and drop them into a spreadsheet or report designed around your requirements.
