Overview

HY-774B sponge compression * deformation device rubber * compression skew compression * deformation amount definition: refers to the difference between the initial thickness of the sample and the final thickness of the sample Z after a specified recovery time after compression at a specified time and temperature. The magnitude of the difference is related to the initial thickness. Principle: Use a fixture to press the sponge to a specified compression amount of 50% of its original thickness, and place it in a constant temperature box adjusted to 70 degrees Celsius. After waiting for 22 hours and the specified time, remove the compressor from it. After removing the sample from the compressor and placing it for 30 minutes, use a specialized microporous material micrometer to measure the thickness and calculate its deformation.
