Technical Data: "Permeation and Cumulative Permeation of Chemical Substances"

Do you know about the important concepts of "permeation" and "cumulative permeation" when selecting chemical protective gloves?

When selecting chemical protective gloves, it is important to understand how the material of the gloves changes when in contact with chemicals and the potential ways in which chemicals can penetrate inside. The indicators for making this assessment are "permeation," "degradation," and "penetration." In particular, "permeation" refers to the phenomenon where chemicals pass through the material at the molecular level, which is not visible to the naked eye. Additionally, another important factor is the "cumulative permeation amount," which indicates "how much of a chemical has passed through the gloves over a certain period of time." While the permeation time (breakthrough time) is important, it is not sufficient on its own; careful consideration of the "cumulative permeation amount" is also required when selecting gloves. This guide explains the following: - The three states in which glove protection is lost: "permeation," "degradation," and "penetration." - Permeation and cumulative permeation.
