Compression Set
Posted on 31/12/2018 Category:
The degree to which a rubber does not recover fully to its original state after it has been compressed for a long period of time. The term is commonly used in reference to a test conducted under specific conditions wherein the permanent deformation, expressed as a percentage, is measured after a prescribed period of time. A low compression set is desirable in moulded rubber parts such as seals and gaskets, which must retain their dimensions to maintain an effective seal.
