The research on encapsulation material of FOLED (flexible organic light emitting diodes) has been a focus of FOLED research both at home and aboard. How to measure water vapor transmission rate , oxygen and other active gases through FOLED  material is one of the important subjects for FOLED encapsulation.  Labthink Instruments Co., Ltd. , as the world renowned testing instrument and testing service provider, introduces the professional FOLED encapsulation material water vapor and gas transmission testing [...]

Moisture Barrier Testing of BOPP Film High moisture barrier performance is a must for flexible package so as to avoid deterioration caused by moisture. At present, this factor is not fully noticed by the flexible packaging manufacturers. Labthink PERME W3/030 is developed according to ASTM E96, ISO 2528 and other standards to test moisture transmission rate for materials. The lower WVTR the better. But, higher barrier property means more costs. Therefore, the common data is less than 10g/m2.day or 5g/m2.day. BOPP [...]

Water Vapor Permeation Testing of Solar Cell Backsheet Film plays the most important role on the quality control of solar cells. The backsheet can protect the photovoltaic components, like solar panel. The main quality of the backsheet is determined by its water vapor barrier property. If the backsheet can not block the water vapor in the air, the vapor will enter and break the bonding force between EVA layer and the panel. When the water vapor contact with solar panel directly, the solar panel will be oxidated and lose its function of generating current.
