Elastomers can be defined as a type of polymer which can be stretched to very high elongation levels under tensile force and immediately return to their initial length when the force is removed.
Purpose of elastomer characterization testing is to determine elastomer’s behavior under static and dynamic loading conditions. Tekno-ETA has extensive experience on testing of elastomer-based products for both characterization and durability testing point of view.
