Test principle
This tester uses the principle of air heating to connect the tested sample to the tension sensor and displacement sensor. After reaching the maximum shrinkage force, it is placed in an external test environment with an ambient temperature of 23°C ± 2°C to cool down, the instrument continuously records the reference temperature, shrinkage force, and displacement, the recorded data can be used to determine optimal shrinkage conditions for the film.
The internal structure of the instrument is shown in Figure 1
