Laser Flash Analysis Thermal Diffusivity Test (LFA)

Product Name Laser Flash Analysis Thermal Diffusivity Test (LFA) Product Overview English Introduction: Laser Flash (LFA) thermal diffusion test is the most accurate and widely used core detection technology in the field of material thermal property characterization. It is mainly used to accurately measure the thermal diffusion coefficient of solid materials, and can accurately convert key thermal indexes such as thermal conductivity and thermal resistance combined with specific heat capacity and density parameters. Based on the principle of pulsed laser transient heating, the technology irradiates the sample surface with instantaneous laser, collects the dynamic change curve of the back temperature of the sample with time, and accurately calculates the thermal diffusion performance of the material. It can effectively characterize the heat transfer and diffusion capacity of various solid materials such as powders, blocks and thin films, and is widely used in new energy, thermal conductive composite materials, thermal insulation materials, ceramics and electronic heat dissipation materials. Equipped with German Netzsch LFA467 professional laser flash tester, this testing service features fast response speed, high test accuracy and excellent baseline stability. High-precision testing can be completed with only a trace amount of powder samples. The test data complies with national and international general testing standards, and can be directly used for scientific paper publication, material thermal performance mechanism analysis, product performance calibration, formula optimization and industrial quality inspection reports.
