Compression-Rebound Performance

Mechanical Properties of Gaskets

As the conclusion of the content about compression-resilience performance, this article focuses on the third analytical dimension of the compression-resilience curve — the area under the curve, as well as the comprehensive evaluation criteria for the compression-resilience of gaskets.

Morphology of the Compression-Resilience Curve

3. Area Under the Curve

First, let's understand the meaning of the area under the curve: The area below the compression curve represents the total work done when compressing the gasket, and this energy is stored in the gasket in the form of elastic strain energy.

BMC modified PTFE sheet gasket has good flexibility

A larger area indicates greater elastic compensation potential of the gasket. On the other hand, the area below the resilience curve is the elastic strain energy released by the gasket during unloading. Obviously, the area enclosed by the curve and the red-colored area represent the rigidity of the gasket.

BMCORIN: Offers flexible dimensions and is suitable for high-temperature and high-pressure working conditions.

When comprehensively evaluating a gasket, we cannot only meet a single requirement. It is necessary to:Ensure appropriate compressibility so that the gasket can adapt to the fitting needs of the sealing surface;Pursue a high resilience rate to ensure timely compensation when the sealing surface separates;Pay more attention to the morphology of the compression-resilience curve. Only a curve with a moderate slope and a reasonable area can enable the gasket to maintain stable sealing performance in actual working conditions.

BMCRIN：Has excellent compression resilience and sealing capability

So far, the content about the compression-resilience performance of gaskets has been fully shared. In the future, we will continue to break down more sealing knowledge. Follow us to obtain more practical sealing technology content.
