Evaluating repeated compression set of polyurethane foam (flexible cellular materials) | FOAM RUBBER REPEATED COMPRESSION TESTER / No.260

Overview of FOAM RUBBER REPEATED COMPRESSION TESTER

This tester is used to repeatedly test compression residual strain of polyurethane foam and latex foam soft material according to the constant displacement method.
Placing the test specimen between the two parallel plates and continuously repeating the compression to the test specimen 80,000 times at a compressing power so that the test specimen’s thickness becomes 50 % of the initial size.
30 minutes after the test specimen has been repeatedly compressed, the decreasing rate of the test specimen’s thickness is to be measured.
