Intercalation is a process whereby an intercallant material is inserted between the graphene layers of a graphite crystal or particle.This material is manufactured by treating highly crystalline natural flake graphite with a mixture of sulfuric acid and certain other oxidizing agents which aid in "catalysis" of the sulfate intercalation.Application:The resultant product is a highly intumescent form of graphite that has proven useful in applications that include fire  retardants, high performance gaskets, conductive fillers, electromagnetic pulse and radiation shielding, foundry products, fire collars, construction industries,and many others.Packing:20/25kgs bags or 800~1000kgs bulk bags on palletsDelivery Time:Within one month after order signed.Payment terms:T/T prefered.L/C is also accepted.Sample is available anytime for your test.
