Conductive silica gel has high conductivity, low surface resistivity (20-500Ω×㎝), stable conductivity, resistance change of less than 10% in one year, high tensile strength, low shrinkage, scratch resistance, high and low temperature resistance (can be used for a long time in -50 to 260 degrees), not easy oxidation and degradation, good chemical stability, but also has excellent hydrophobic, moisture-proof, Earthquake resistance and physiological inertia.
