TO ADJUST PVB INTERLAYER MOISTURE BY ENVIRONMENTAL HUMIDITY

According to the chemical formula of Polyvinyl Butyral shows, PVB film is a hydrocarbon and an absorbent material. Its moisture changes by environmental humidity and time if PVB film exposed in the air, when absorbent material is exposed to a certain temperature and humidity environment, moisture will be transferred from each other between the absorbent material and the air, until reached moisture equilibrium between absorbent material and environment, so may adjust environmental moisture can be changed PVB film moisture in storage.

According to moisture balance, final moisture can be determined under the relative humidity. In order to ensure PVB moisture content, new opened PVB film or roll must be stored at cleaning room where humidity around 23%~28%, temperature 20 ~ 25 ℃ over than 24 hours, PVB film moisture content reach standard then laminating.
