Tensile Tests of Rubber Dumbbell Specimens

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 three synthetic rubber (main components: chloroprene [1]; urethane [2]) specimens (dumbbell shaped test specimens). Static tensile tests were performed, and the specimens were evaluated with respect to tensile strength, stress at given elongation, and elongation at break, which are aspects of their basic mechanical properties.
