WebbStress relaxation testing measures when a constant stress creates a physical and/or chemical change in a plastic or rubber material, thus reducing the force that the polymer compound can exert over a specified period of time. The first observed effects generally include the relaxation of polymer chains and fillers. Webb1 feb. 2024 · A thermoplastic, or thermo softening plastic, is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. Thermoplastics differ from thermosetting polymers (or “thermosets”), which form irreversible chemical bonds during the curing process.
