PE composite diaphragm is made of special glass fiber felt for PE diaphragm and battery diaphragm by composite process. It has good mechanical strength and vibration resistance, and can effectively prevent the active substance from falling off the plate. It is suitable for maintenance free batteries and power batteries.
