Expandable graphite is a unique form of graphite that possesses the ability to expand when exposed to heat. This expansion is due to the intercalation of gases or vapors between the layers of graphite, resulting in an increase in volume. Here are the specifications and properties of expandable graphite:
Chemical Inertness: Expandable graphite is chemically inert, meaning it is resistant to chemical reactions with most substances. This property allows it to maintain its stability and expandability in various environments.
Thermal Conductivity: Graphite, in general, has excellent thermal conductivity, and expandable graphite retains some of this property even after expansion. This makes it useful in applications where heat transfer is desired, such as in insulation materials.
Particle Size: Expandable graphite is available in various particle sizes, ranging from fine powders to larger flakes or granules. The particle size can affect the expansion characteristics and handling properties of the material.
Applications: Expandable graphite is widely used in numerous applications, including flame retardant materials, gaskets and seals, insulation materials, thermal management products, and as an additive in polymers, plastics, and coatings.
It's important to note that the specifications and properties of expandable graphite can vary depending on the specific product, manufacturing process, and intended application.
