SIGRATHERM® Water Based Graphite Dispersions Grade A
Description
Dispersions based on expanded graphite powders and graphite nanoplates.
Expanded graphite nanoplates consist of small, 1-15 nanometer thick, single or multilayer graphite layers, with diameters up to 100 micrometers. They constitute a new class of graphite nanoparticles with multifunctional properties. In order to obtain a graphite dispersion, small graphite particles and nanoplates produced by secondary treatment of our expanded graphite are mixed with a dispersant in water. Depending on the application, the viscosity of the dispersion can be adjusted by means of different concentrations of solids. The maximum dispersible solid content is 5.5% by weight.
Key characteristics of our graphite nanoplates are:
- Excellent layer formation on a variety of substrates, e.g. copper foil or PET film
- The high aspect ratio of the graphite nanoplates allows high electrical and thermal conductivity
- Freestanding graphite foils with a thickness between 5 and 15 μm can be produced

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
