Rubber materials have characteristic mechanical properties including elasticity and flexibility, and are widely used for industrial parts, construction materials, and housewares. In particular, a diverse range of synthetic rubber materials with differing properties suited to match their application have been developed. Measuring these mechanical properties is extremely important to ensure quality control and for new materials development. This Data Sheet introduces an example of the evaluation of two synthetic rubber specimens (crescent-shaped specimens). Tear tests were performed, and the specimens were evaluated with respect to
tear strength, one of their basic mechanical properties.
