Use

Temperature cycling Chamber reflects the heat resistance of materials by accelerating the aging process under the action of oxygen and heat.Oven aging test is a common method of heat resistance test. The temperature is determined according to the material requirements and experimental purposes.The upper limit of temperature can be determined according to relevant technical specifications. Generally, for thermoplastic materials, the temperature should be lower than their vicat softening point; for thermosetting materials, the temperature should be lower than their thermal deformation temperature; or, through exploration experiments, the temperature that does not cause sample decomposition or obvious deformation is selected.The samples were placed in a hot oven under selected conditions, and the changes in appearance and properties of the samples were periodically checked and tested, so as to evaluate the heat resistance of the samples.This method is commonly used in plastics and rubber and is also commonly used in heat resistance tests of information recording media.The main experimental methods are hot air exposure of plastics, vulcanized rubber or thermoplastic rubber, hot air accelerated aging, heat resistance test and heat resistance test of paint film.
