Expandable Graphite By Qingdao Sunray Carbon

We commence our business operation as a renowned supplier of Expandable graphite in Qingdao, Shandong, China. Expandable flake graphite, also known as intumescent flake graphite, or simply a expandable flakea , is a form of intercalated graphite. Intercalation is a process whereby an intercallant material is inserted between the graphene layers of a graphite crystal or particle. After intercalation the resulting graphite material takes on new properties that are a function of the intercallant and the way it associates with the host (graphite) species. Both physical and chemical properties, including crystallographic structure, surface area, density, electronic properties, intumescent behavior, chemical reactivity, etc., may be affected by the intercallant. A wide variety of chemical species have been used to intercalate graphite materials.
