1、 Features and uses
The compression heat generation testing machine is used to determine the compression heat generation and fatigue performance of vulcanized rubber, and is suitable for vulcanized rubber with a hardness less than 85IRHD. This machine applies a specified compression load to the sample through a balancing lever, and periodically compresses the sample with a certain amplitude and frequency. Measure the fatigue heating, static compression deformation rate, dynamic compression deformation, permanent deformation, and fatigue life of the specimen within a certain period of time. Complies with the requirements of GB 1687-93 \ ASTM-D623, ISO4666/3-1982, HG/T2070 and other standards.
