Expandable graphite (acidified graphite)
Expandable graphite (acidified graphite), a graphite intercalation compound obtained from natural crystalline flake graphite treated with an acidic oxidizing agent,is also known as graphitic acid, acidified graphite, or graphite oxide.
1.EPS board and coating
Expandable graphite for EPS is mainly used in EPS board and coating, which has the functions of heat preservation, waterproof and fire prevention.
2.Fireproof sealing strips
Due to its expandability and high temperature resistance, expandable graphite has become an excellent sealing material and is widely used in fireproof sealing strips.
3.Flame retardant plastic
the expanded carbon layer formed by expandable graphite carbon has excellent heat insulation performance and high-temperature resistance.Expandable graphite is the only one that can be used in harsh conditions and has enough expansion strength.
4.Fireproof bag ,fireproof blocking material
because of the high expansion rate of expandable graphite at high temperatures,it can be used as an effective intumescent flame retardant material to make fire-proof packages and fire-proof plugging material
5. Fire board
expandable graphite is used in the mixture of the fire-proof board,in order to increase the fire-proof performance of the board ,reduce the density of the board and enhance the heat insulation performances.
6.battery material
As a battery material, expandable graphite is converted into electrical energy by the change of free energy of the interlayer reaction of expandable graphite.
7.flame retardant coating
Expandable graphite is trying to be used in flame retardant coating ,which can give coatings excellent thermal expansion.The coatings overcome the shortcomings of the the previous coatings which are easy to produce smoke.
