Methane Carbon Black Performance Specifications:

2. Iodine Adsorption Value g/kg: The iodine adsorption value measurement of carbon black is a common method to determine the specific surface area of carbon black. Method: Immerse a quantitative sample of carbon black in a standard iodine solution of a specified concentration, mix it thoroughly, and wait until it reaches equilibrium. Separate the carbon black from the iodine solution and titrate the concentration of the iodine solution. Calculate the ratio of the adsorbed iodine amount to the amount of carbon black, which is the iodine adsorption value of the carbon black.

4. Resistivity Ω.cm: Resistivity is a physical quantity used to express the resistive characteristics of various materials. The resistance of a wire made of a certain material, with a length of 1 meter and a cross-sectional area of 1 square millimeter, at room temperature (20℃), is referred to as the resistivity of that material. The unit of resistivity is ohm-meters (Ω.cm or ohmm), with common units being ohm-millimeters and ohm-meters.

6. Heating Loss %: Some substances are not completely pure and tend to absorb moisture, causing the concentration of active ingredients to decrease upon heating. The amount of reduction is referred to as the heating loss.
