What Does Outgassing Mean?

Outgassing is the release of a gas that was dissolved, trapped, frozen, or absorbed in some material. Outgassing can include sublimation and evaporation, as well as desorption, seepage from cracks or internal volumes, and gaseous products of slow chemical reactions.

What does outgassing mean in science?

Outgassing is a concern for any electronic equipment intended for use in high-vacuum environments. It refers to the release of gas trapped within a solid, such as a high-frequency circuit-board material.

What is outgassing and why is it important?

Outgassing is usually most relevant in vacuum applications, where the vacuum causes the elastomer to release constituent material. ... A seal material with low outgassing is essential because it shows the seal material does not emit volatile constituents under vacuum conditions.
