Insulating sheets are a type of electronic insulating material with low electrical conductivity, used to isolate materials with different potential electrical charges. Next, let's delve into the product characteristics of insulating sheets.

Flame Retardancy: Refers to the ability of insulating materials to resist combustion when in contact with fire or to prevent continued combustion when removed from the flame. With the ever-expanding applications of insulating materials, the demand for their flame retardancy has become increasingly critical.

2. Arc Resistance: The ability of an insulating material to withstand the application of an arc along its surface under specified test conditions. The test employs AC high voltage and low current. The time required for a conductive layer to form on the surface of the insulation due to the arc produced by the high voltage between the two electrodes determines the arc resistance of the insulating sheet. The higher the time value, the better the arc resistance.

3. Sealing Efficiency: Insulating sheets offer excellent utility for sealing against oil and water quality.

4. Insulation Resistance and Resistivity: Resistance is the reciprocal of conductivity, and resistivity is the resistance per unit volume. The poorer the material's conductivity, the higher its resistance, and there is an interrelation between the two. For insulating sheets, there has always been an expectation for as high a resistivity as possible.
