Expandable graphite shines in the field of fire retardant materials
Expandable Graphite is a special graphite material, which has good thermal expansibility and can expand rapidly under high temperature conditions. Expandable graphite can instantly expand several times or even tens of times at a high temperature of 400~500℃ and has a high expansion rate and expansion stability. Strong adsorption capacity can be adsorbed on the surface of various organic and inorganic substances, with strong fire and heat insulation performance. High chemical stability and low conductivity can be used in strong acids, weak bases, high temperatures, and other harsh conditions. In addition, expanded graphite also has strong pressure resistance, flexibility, plasticity, and self-lubrication, as well as high and low-temperature resistance, corrosion resistance, radiation resistance, and seismic characteristics. At the same time, it can resist the melting and penetration of various metals, is non-toxic, does not contain any carcinogens, and does not harm the environment.
Expandable Graphite
With the continuous progress of science and technology and the rapid development of industry, the demand for fire retardant materials is increasing. Recently, a material called Expandable Graphite (EG) has shown excellent performance in the field of fire prevention and flame retardant, which has attracted wide attention.
Expandable graphite is a special graphite material; through the introduction of a special oxidizing agent or substance in the graphite crystal, it can undergo an oxidation reaction at high temperatures, produce gas, and cause the expansion of the graphite crystal. This expanded graphite can expand rapidly at high temperatures to form a dense carbonized layer, effectively isolating the contact between flame and oxygen so as to achieve the effect of fire prevention and flame retardant.
In the field of fire retardant materials, expandable graphite has a wide range of applications. For example, in wire and cable, adding expandable graphite can enhance its flame-retardant performance and effectively prevent the spread of fire. In building materials, expandable graphite can be used to make fireproof coatings, fireproof panels, etc., to improve the fire rating of buildings. In addition, in the aerospace, transportation, and other fields, expandable graphite also plays an important role.
According to the latest reports, in recent years, the application of expandable graphite in fire retardant materials has made great progress. In addition to traditional fire rings, smoke bars, fire doors, and other conventional products, some new applications are also increasingly widespread. For example, in the seats of aircraft, trains, and other vehicles, PU foam with expandable graphite has been widely used to improve the flame-retardant performance of the seats. In the asphalt coil used in the roof, the expansible graphite also occupies a place, which effectively improves the fire resistance of the roof.
Expandable graphite is used as fire retardant material
Experts said that expandable graphite, as an efficient and environmentally friendly fire-retardant material, has broad market prospects and application prospects. With the continuous progress of technology and the continuous expansion of application fields, expandable graphite will play a greater role in the field of fire prevention and flame retardant.
