Powder Resistivity Test

Product Name Powder Resistivity Test Product Overview English Introduction: Powder resistivity is a core physical property index for characterizing the electrical conductivity, insulation performance and charge transmission capacity of powder materials, and it is a key test item for the R&D and quality inspection of conductive powders, insulating fillers, new energy electrode powders and functional composite powders. The powder resistivity test can accurately quantify the volume resistance, resistivity and conductive characteristics of powders under compacted state, and directly reflect the conductive path construction ability, filler conduction efficiency and insulation barrier performance of powder materials. It is widely used in conductive functional materials, energy storage battery materials, electronic packaging fillers, polymer composite conductive materials and anti-static powder materials. Adopting the special powder resistivity test equipment Suzhou Jingge ST2272 and based on the standard four-probe test principle, this test compacts powder samples under constant pressure to simulate actual application working conditions and accurately detect powder volume resistivity parameters. With standardized test operation and strong data repeatability, the test can be completed with a powder volume of at least 2mL. The test data complies with general industrial test standards, and can be directly used for scientific paper publication, material conductive mechanism analysis, powder formula optimization, conductivity/insulation performance calibration and industrial quality inspection reports.
