Thermal Conductivity Test

Product Name Thermal Conductivity Test Product Overview English Introduction: Thermal conductivity test is a core physical property detection technology for characterizing the thermal conduction performance, heat transfer efficiency, heat insulation and heat dissipation capacity of materials. It is a key test item for the R&D and quality inspection of new energy materials, thermal insulation materials, polymer composite materials and powder functional materials. Based on the core principle of laser flash method and relying on the Mettler DSC1 + Netzsch LFA467 synchronous test system, this test can accurately measure the in-plane and out-of-plane bidirectional thermal conduction properties of materials, and obtain core thermal parameters such as thermal conductivity, thermal diffusion coefficient, specific heat capacity and thermal resistance of samples. It can objectively evaluate the heat conduction, heat dissipation and thermal insulation performance of materials. The test is highly suitable for various powder functional materials. Through precise temperature control and laser transient thermal response collection, it avoids the problems of large error and poor repeatability of traditional steady-state tests. The test data features high accuracy and good stability, which can be directly used for scientific paper publication, material thermal conduction mechanism analysis, product heat insulation and dissipation performance calibration, new material formula optimization and industrial quality inspection reports.
