Expandable Graphite is also called flexible graphite, made of high quality natural flaky graphite through special chemical modification at high temperature, and has the expansion ratio from 100 to 400 ml/g.

Advantages:

The product has natural flaky graphite property, and such characteristics as good expansibility, pressure resistance, forming plasticity, self-lubrication, flexibility and extensibility and sealing performance.finished product has high temperature resistance, anti-corrosion, radiation protection, thermal insulation, lubrication, chemical stability, etc.

Usage:

The product has even particle size distribution and stable quality, and is high quality raw material for various graphite plate and sealing members. It is also used as novelty protecting slag, exothermic compound and flame retardant etc., for metallurgical industry, and widely used in high-tech industry field, such as petroleum, chemical, light industry, medical care, electric power, aviation, automobile,shipbuilding, instruments, military industry, nuclear energy, etc.
