Expandable Graphite: Innovative Materials Leading a New Revolution in Fire and Insulation

Expandable graphite is a special type of graphite material. After chemical treatment and high-temperature expansion, it can form graphite "worms" with a volume that can expand 100-350 times. This material has excellent characteristics such as being lightweight, having good conductivity and thermal conductivity, high-temperature resistance, nontoxicity, and chemical stability.When expandable graphite reaches a certain temperature when heated, it begins to expand due to the decomposition of compounds in the interlayer lattice, and this process is called the initial expansion temperature. At 1000 ℃, expandable graphite will completely expand and reach its maximum volume. The expanded graphite is called expanded graphite or graphite worm, which changes from a flake-like structure to a low-density worm-like structure, forming a very good insulation layer. This material has the characteristics of a low heat release rate, small mass loss, and less smoke generation in fires.

Recently, an innovative material called "expandable graphite" has attracted widespread attention in the field of fire insulation.

Expandable graphite, as a special type of graphite material, has the characteristic of rapidly expanding and forming an insulation layer at high temperatures. This characteristic makes it show great potential for application in the field of fire prevention and insulation. When a fire occurs, expandable graphite can quickly expand and cover the fire source, forming a dense insulation layer that effectively prevents the spread of the fire and heat transfer.

Expandable graphite is widely used in the field of building fire protection, such as fire doors and windows. Traditional fireproof materials often have problems such as heavyweight and easy detachment, while expandable graphite has advantages such as lightweight, easy construction, and high-temperature resistance, which can greatly improve the fireproof effect. Meanwhile, expandable graphite also has good environmental performance.

In addition to the field of building fire prevention, expandable graphite also has broad application prospects in energy, chemical, and other fields. In the field of batteries, expandable graphite can be used as an electrode material to improve the energy density. In the field of chemical engineering, expandable graphite can be used as an adsorbent material for treating pollutants such as wastewater and exhaust gas.

Industry experts indicate that expandable graphite, as a new type of fireproof and thermal insulation material, has broad market prospects and application potential. With the continuous progress of technology and the expansion of application fields in the future, expandable graphite will undoubtedly play a more important role in the field of fire prevention and insulation.
