    Measurement of Plastic and Rubber Hardness The hardness of plastics and rubbers is often measured by the Rockwell or Shore (durometer) hardness methods The correlation between the different Rockwell scales used for plastics is rather poor and, therefore, conversion between the scales is discouraged, that is,

    There are a number of different tests to measure the relative hardness of different materials These tests are predominantly used as a measure for thermoplastic rubber types of plastic as a means of comparing softness and flexibility There are three main types of test Rockwell, Ball and Shore Hardness Results from
