Low compression set
compression set (iii)
To obtain these characteristics, good resistance to compression set (that is, the material must recover to its original size and shape sufficiently when re- leased) is required.
The critical condition for maintaining a positive contact pressure is when the joint is fully open at low temperature since compression set or lack of low temperature recovery may adversely affect sealant performance.
