Product Description

High Purity Graphite Is High Expand Multiple Expandable Graphite Powder

Expandable graphite can expand rapidly when heated at high temperature, and the expansion multiple is as high as tens to hundreds or even thousands of times. The apparent volume of expanded graphite is 250-300mL/g or larger, and the expanded graphite is worm-like.

 

The size is between a few tenths of a millimeter and a few millimeters, and it has a large number of unique network-like microporous structures inside, which are called expanded graphite or graphite worms. In addition to the excellent properties of natural graphite, such as cold and heat resistance, corrosion resistance, and self-lubrication, expanded graphite also has softness, compression resilience, adsorption, ecological environment coordination, biocompatibility, and radiation resistance that natural graphite does not have.

 

Expandable graphite and its expanded graphite can be used in iron and steel, metallurgy, petroleum, chemical machinery, medical, aerospace, atomic energy and other departments, and has a wide range of applications.
