LT-JJ36-B Sponge Repeated Compression Testing Machine

Short Description:

This machine determines the compression set of cellular materials by performing repeated compression cycles. After precisely measuring the specimen’s initial thickness, it is placed between the compression plates. The specimen is then subjected to reciprocating compression at a frequency of 60 cycles per minute, where it is compressed to 50% of its original thickness for 80,000 cycles. Following the test, the specimen is allowed to recover at ambient temperature for 30 minutes. The final thickness is then measured, and the compression set (permanent deformation) rate is calculated.
