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:
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.
Composition: Expandable graphite is primarily composed of graphite flakes, which are layers of carbon atoms arranged in a hexagonal lattice structure. The graphite flakes are typically chemically treated to enhance their expandability.
Expansion Ratio: The expansion ratio refers to the increase in volume that expandable graphite undergoes when exposed to heat. It can range from several times to hundreds of times its original volume, depending on the specific product and processing conditions.
Thermal Stability: Expandable graphite exhibits good thermal stability, allowing it to withstand high temperatures without significant degradation. It can typically withstand temperatures up to several hundred degrees Celsius without losing its expandability.
Flame Retardant Properties: One of the notable properties of expandable graphite is its excellent flame retardancy. When exposed to heat or flames, the expansion of the graphite forms a protective layer that acts as a barrier, slowing down the spread of fire and reducing heat transfer.
Low Density: Expandable graphite has a relatively low density, which contributes to its lightweight nature. This property makes it suitable for applications where weight is a consideration.
