Fiberglass diameter; 2-4 micron
Slag content: 0.2%
Thermal conductivity (under room temperature): ≤0.028 w/m. K
High chemistry purity and acid resistance, weight loss (under 25C, temperature and sulfuric acid electrolyte with specific gravity 1.28): 3%;
High porosity, massively electrolyte to be adsorbed and good at capillarity property, and sulfuric acid electrolyte with specific gravity 1.28 will increase more than 100mm within 5 min;
The porosity is higher than 94%;
The distribution of pore is even, the biggest aperture is less than 17um;
The resistance is lower than 0.0003;
Elongation ratio: 3%;
Thickness: 0.3-3.0mm (under condition of 10Kpa thickness measurement device)
Mainly used in AGM battery separators, air filters, etc.
