Applications:

This equipment is designed to perform dynamic tensile testing (or De Mattia flex cracking testing) on rubber specimens under both high- and low-temperature conditions.

For dynamic tensile testing, the device is equipped with a specimen break detection function, using a force sensor as the detection method. Compared with traditional detection methods, it offers advantages such as enhanced safety and reliability, no noise, and no requirement for specific lighting conditions.
