It is important to note that hardness values should only be used as a point of reference if being compared on the same scale. Do not compare Shore A values with Shore D values to make material selections, as the slope of hardness values from 0 to 100 differ greatly between the two scal...

Shore A: The most commonly used category providing a wider range of hardness. This scale measures flexible mold rubbers that range from very soft to exceptionally hard rubbers with almost no flexibility. Some semi-rigid plastics can also fall onto the higher end of the scale. Shore D: Includes...
The Shore A scale is used for “softer” rubbers while the Shore D scale is used for “harder” ones. This method works better for thicker coatings, as with all hardness tests on coatings. The hardness of thin coatings can be influenced by the substrate, that is, an artificially hard ...
Shore Hardness, using either the Shore A or Shore D scale, is the preferred method for rubbers/elastomers and is also commonly used for 'softer' plastics such as polyolefins, fluoropolymers, and vinyls. The Shore A scale is used for 'softer' rubbers while the Shore D scale is used for '...
