Fiberglass AGM Battery Separator
AGM separator is one kind of environmental-protection material which is made from micro glass fiber(Diameter of 0.4-3um). It is white, innocuity, tastelessness and specially used in Value Regulated Lead-Acid batteries(VRLA batteries). AGM spacer is an ultra-fine glass fiber spacer, featuring small aperture, large number of holes, good mechanical strength, acid

1. large liquid absorption capacity, liquid absorption speed block, good water permeability, absorbing and maintaining the electrolyte of the rated original capacity of the battery.
2. Large surface area and high porosity, even if the electrolyte is poor, it can ensure that the oxygen generated at the positive electrode can diffuse to the negative electrode through the spacer and combine with the sponge lead on the pole plate.
3. Small pore size can effectively prevent short circuit of the battery.
4. High chemical purity, does not contain any self-discharging impurities
5. Excellent acid resistance and oxygen resistance.
6. Low resistance.
