On the Application of Vickers Micro Hardness Testing to Isotactic Polypropylene. [PDF]
Polymers (Basel), 2022 Hardness is a useful measure of a material’s resistance to permanent indentation; but for viscoelastic polymers, hardness data are highly dependent on the test type and the parameter set chosen. Vickers microhardness testing is used to leave small indents (<150 µm) and is shown to be applicable to polymers.
