c which is made of micro glass fiber (Diameter of 0.6-6μm). It is white, innocuity, tastelessness and specially used in Value Regulated Lead-Acid batteries (VRLA batteries). The AGM separator has good acid resistance, equal thickness, high volume porosity, enough tensile strengthen 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 from falling off, slow the creation of lead crystal, and reduce the loss of electrolyte in charge & loss maintenance, it is also has a long using life. The AGM separator is supplied in rolls or pieces, and packed with carton after covered with the plastic film. Application: UPS power supply, Electrical power system, Railway signal
