Splet2.2.3 Hardness-Shore (A) The hardness test is used for measuring the relative hardness of soft materials and is based on the penetration of a specific indentor forced into the material under specified conditions. The hardness shore (A) is measured using the hardness tester ZWICK (model- 3102) at 25 °C. According to Splet17. apr. 2024 · For PDMS with paraffin, a mean hardness value of 33.2 ± 1.03 Shore A was obtained, and for PDMS with beeswax, 28.0 ± 1.05 Shore A, values 20.38% and 32.85% smaller than the pure PDMS, respectively. This behavior was also presented in other past works where they have studied composites with a polymeric matrix and wax addition.
