Compression Set ( Temperature Dependence)

Compression Set ( Long-term Continuous Compression)

A sample is compressed 50% at each temperature and allowed to stand for 22 hours.
After releasing the compression, leave it for 30 minutes, and measure the compression set.

The sample is compressed by 50% and left at 80℃. After a predetermined time, the pressure isreleased and after 30 minutes, the thickness is measured to calculate the compression set.
