Expansible graphite is a kind of graphite product used in the field of flame retardant and fire retardant. The specifications of expansible graphite used in different flame retardant products are different.
Expansible graphite has the characteristics of high resistance, low temperature, pressure resistance, self-lubrication, corrosion resistance, flexibility, plasticity, earthquake resistance, etc. Expansible graphite specifications generally have 50 mesh, 80 mesh, 100 mesh and other specifications, flame retardants use expandable graphite as a new type of intumescent flame retardant additives, flame retardants use expandable graphite anode has its own. The flame retardant is different from other expansive graphite. When the flame retardant is subjected to high temperature above 200 C, the flame retardant begins to expand with expansible graphite due to the decomposition of compounds in the interlayer lattice. The expanded graphite rod becomes worm-like with very low density and forms very good flame retardant. Expansible graphite for insulation and flame retardant has the advantages of low heat release rate, low mass loss, less smoke and non-toxicity in fire.
Expansible graphite (EG) can be used to produce various fire-retardant products. One of them is EG used as flame retardant. Different flame-retardant products need different specifications of EG.
