Mechanical Behavior of Gaskets
（Compression-Recovery Performance）
In today's communication and discussion, we will focus on the mechanical behavior properties of the important component - gaskets. Specifically, we will mainly discuss two key characteristics of gaskets: Compressibility and Resilience.
●Compressibility and Resilience●
What is Compressibility?
Simply put, compressibility refers to the change in the thickness of a sealing gasket after initial compression. It can directly reflect the rigidity of the gasket. The greater the compressibility of the gasket, the easier it is to deform.

What is Recovery?
Recovery is defined as the change in the thickness of the gasket that can be restored after the compressive load is removed. This characteristic plays a crucial role in the actual operation process. Because it can effectively compensate for the separation between the sealing surfaces caused by changes in medium pressure or other external factors. Through this compensation mechanism, it can ensure that the joint always maintains good sealing performance, thereby avoiding problems such as leakage.

Compared with compressibility, recovery is more important for maintaining the sealing effect. Even if the gasket has compression performance during initial installation, if its recovery is insufficient, it will be difficult to adapt to the dynamic changes of the sealing surface during long - term use, affecting the sealing reliability. Therefore, the performance of recovery directly determines whether the sealing system can operate stably under various working conditions, and its importance far exceeds that of compressibility.
In the next article, we will specifically talk about how to accurately obtain the compression and recovery data of gaskets through standard tests.
