WVTR (Water Vapor Transmission Rate) evaluation (Collaborating with MORECSO)

@Home Λ Technology Λ WVTR evaluation

 

Ø We provide WVTR (Water Vapor Transmission Rate) evaluation, using the WVTR measurement equipment gSuper Detecth of MORESCO.

Ø The gSuper Detecth utilizes the MA method (Modified differential pressure method with an Attached support) developed by the collaboration of MORESCO and AIST (National Institute of Advanced Industrial Science and Technology).

Ø The MA method reduces measurement time of high gas barrier film such as higher than 10-4 g/(m2 day), which are required in flexible OLED, OPV, etc.  For example, the gSuper Detecth requires only about 20 hours for the WVTR measurement of barrier films with the order of 10-5 g/(m2 day), for which the previous methods require about 100 hours.  It should be noticed that the measurement time of the gSuper Detecth is only 1/5 of previous methods. 

Ø In addition, the gSuper Detecth is able to evaluate wide ranges of WVTR such as 10+1~10-7 g/(m2 day).

Ø The gSuper Detecth with the MA method is able to warrant the WVTR value by the attached compensating unit developed by AIST.

Ø Moreover, the gSuper Detecth is able to evaluate the transmission rate of not only water vapor but also various gasses.
