The Constant Deflection Compression Tester measures the change of thickness of a polyurethane. The size of sample 50mm x 50mm. This is after deflecting the test piece to a specified deflection. This is for a certain amount of time and temperature. The process to test sample includes compressing it at a certain deflection, time and temperature. This allows measurement of thickness loss after the specific recovery period. Thus, the Constant Deflection Compression Tester determines the quality of polyurethane. The Compression device comes with two flat plates placed parallel to each other by bolts. The space between the plates is adjustable using spacers. Thus, suiting different sample thicknesses.
