Expandable Graphite

Product Detail

Lushun Huitong is one of the professional expandable graphite manufacturers and suppliers in China, welcome to buy expandable graphite from our factory.

Expandable Graphite                  

The Expandable Graphite still retains the characteristics of natural flake graphite, and also has good expandability, loose and porous. Its heat-resistant range under the oxygen-free environment is between -200 to 3000?, and it is chemically stable under high temperature, pressure or radiation. When the Expandable Graphite was treated in a twinkling at high temperature, the form of flake is turned into that of worm, and the volume can expand from 100 to 400 times.

Particle size:32,50,80,100,-100,-200,-325mesh.

Expansion ratio:100-400ml/g

Properties:good expansiveness,high temperature resistant,radiation protection,thermal insulation,lubrication,plasticity,and chemical stability.
