PE composite separator

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.

Applicable battery range ● High vibration type battery ● Taxi type battery ●Tractor and construction machinery batteries

Baffle characteristics ● Suitable for packaging into bags and sheets Vibration resistance, improve mechanical performance ● High porosity ● Low resistance ● Aperture good corrosion resistance
