Methane Carbon Black Performance Specifications:

2. Iodine Adsorption Value g/kg: The iodine adsorption value test for carbon black is a commonly used method to determine the specific surface area of carbon black. Method: Immerse a predetermined amount of carbon black sample in a solution of iodine standard at a specified concentration, mix it thoroughly, and wait until it reaches equilibrium. Then, separate the carbon black from the iodine solution and titrate the concentration of the iodine solution. Calculate the ratio of the amount of iodine adsorbed 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 properties of various materials. The resistance of a wire made of a certain material, 1 meter long and with a cross-sectional area of 1 square millimeter, at room temperature (20℃), is called 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 highly pure and tend to absorb moisture, causing a reduction in the effective components upon heating. The amount of reduction is referred to as the heating loss.
