Purpose:Satisfy customers with the analysis of permanent compression tests and accelerated aging tests for various sponge samples.

Principle:Maintain a constant deformation of the sample at a specified temperature for a specified time, and observe the change in thickness of the sample after recovery. Place the sample in an environment with the corresponding temperature for a certain period of time and observe its morphology and internal changes.
