One of the main reasons supporting the creation of VIPA International was the need to speed up the standardisation process hereby solving some of the technical matters about the use of this technology in different applications. VIPA International financed the following projects:
An Advanced Technique for Measuring the Effect of Moisture Content on the Thermal Conductivity of Fumed Silica VIPs and the Equilibrium Water Vapor Pressure of Desiccants
Commissioned to: Avery Dennison Hanita, Israel
Timeframe: July 2019 to November 2020
Description of the project:The degradation rate of VIPs depends not only on the permeation rate of the different atmospheric gases through the envelope, but also on the response of the core material to the increasing presence of these permeated gas molecules. Field tests on fumed silica (FS) panels show that the degradation rate of FS panels is predominantly determined by the moisture permeating through the envelope, and much less by the permeating air molecules. In this project, Avery Dennison Hanita analyzed four different fumed silica cores and three different types of desiccants which are commonly used with glass fiber cores.
