Water Vapor Permeation Testing Of Ultra-Barriers
By MOCON, Inc.
Advancements in barrier quality of certain materials have pushed the sensitivity limits of commercially available water vapor permeation equipment. In order for products to be viable, current permeation testing methods must be enhanced or altered. In designing a more sensitive method, the limitations of the current methods were studied. From there, enhancements and modifications to the traditional comparative or concentration sensor produced an order of magnitude increase in sensitivity. Permeation results illustrating the new system will be presented as the highlight of the paper.
