Kuraray Americas EVAL EVOH layer has been proven to be an exceptional barrier to gases, including volatile organic compounds (VOCs). In geomembranes, EVOH layer greatly enhance the gas barrier performance of the membranes. (Geomembranes in general are engineered for liquid impermeability. Gas transmission rates can remain elevated; hence, the need for improved gas barrier performance.) Learn more about EVOH’s role in this updated introduction to EVOH and Geosynthetics from Kuraray America (PDF).
