Expandable Graphite DP1000

Expandable graphite is a kind of graphite product that takes natural flake graphite as raw material and is treated by chemical or electro-chemical technology.When it is under high temperature, it can expand instantaneously,flake graphite becomes vermiform gtaphite,which is loose in structure,porous,curved,with larger surface area,high surface energy and strong adsorptive power.Themselves can inlay the vermiform graphite pieces.In this way,its flexibility,resilience and machinablility are increased.It is high-quality material fot making flexible graphite sheets and various sealing components;it can also be used for heat preservation in metallurgical industry and as fire-extinguishing agent for fire fighting.The development of low temperature expandable graphite probides new method for the development of fire prevention material
