T-R Tester
The Low Temperature Retraction Tester evaluates the temperature at which a specimen reaches a certain specified contraction ratio while the temperature of the specimen, which has been stretched to a certain level and frozen at a low temperature, is raised at a certain constant rate. The TR test is mainly used to determine the elastic recovery characteristics at a low temperature of the materials of which sealing performance is required, such as rubber seal components, hose etc.
