Tappi Place White Papers
PFFC brings you exclusive whitepapers from Tappi Place about Water Vapor Testing of Ultra-Barriers, the limitations of current methods and advancements leading to increased sensitivity, and also about mapping the double-layer lay-flat measurement to the rotating bubble to provide discrimination of various Polymer layers.
Water Vapor Permeation Testing of Ultra-Barriers:
Limitations of Current Methods and Advancements Resulting in Increased Sensitivity
Advancements in barrier quality of certain materials have pushed the sensitivity limits of commercially available water vapor permeation equipment. In order for products such as OLED’s which incorporate these high barrier materials, to be viable, current permeation testing methods must be enhanced or altered.
Thermo Fisher Scientific White Paper
This paper focuses on a new technique of precisely mapping the double-layer lay-flat measurement to the rotating bubble to provide discrimination of various Polymer layers using the Full Spectrum Infra Red sensor technology.
