Through instant process in high temperature, volume of the product can become from 100 to 400 times than that of the original.

Expansive graphite that is specially processed is a good new type airproof material.Through instant process in high temperature, expansive graphite has become from squama to worm-shape with volume 100 to 400 times than that of the original. Besides ,with the characteristics of natural Flexible graphites' property, good plasticity, ductility and airproof ability. It can be used as raw material of graphite and sealed piece, as well as new covering slag and calorifacient reagent in metallurgy.
