Compression set

The compression set is a measure of how elastomers behave during long-lasting, constant compression deformation and subsequent relaxation.

According to DIN 53517, DIN ISO 815 or ASTM D 395, the compression set is measured at constant deformation. This represents the deformation component of the test material. Many test procedures for elastomers, such as tensile strength, characterize the quality and composition of the material. DVR, on the other hand, is an important factor that must be considered before using a material for a particular purpose.
