The AGM separator is one kind of environmental-protection material made of micro glass fiber , which is white, innocuity, odor-free and specially used in Valve Regulated Lead-Acid batteries (VRLA batteries).
AGM separator has good acid resistance, equal thickness, high volume porosity, enough tensile strength both in machine direction and cross direction, good compression ability to ensure the high plate group pressure, and good insulative ability etc. It can absorb enough electrolyte, supply the channels for hydrogen and oxygen free passing to react, prevent the active materials falling off from plates, slow the creation of lead crystal, and reduce the loss of electrolyte in charge & discharge progress, so that the batteries using the AGM separator are free-maintain or just need less maintenance, and have a long using life.
The AGM separator is supplied in rolls or pieces, and packed with carton after covered with the plastic film.
