Using this instrument, indentation hardness is calculated from the results of one load/unload process. The specimen information utilized in the measurements can be observed in Table 2. PP, HDPE, ...

Therefore, all these instruments measure only the hardness after the load has been removed, that is, plastic hardness. With elongated indenters and partly with square-base pyramid indenters ...

Increasing the surface hardness of many materials opens them ... scratch and abrasion resistant coatings for plastics, antistatic films plus colour decorative coatings for glasses and plastics.
