EXPANDABLE GRAPHITE-HIGH PURITY

Expandable graphite is made from natural flake graphite through chemical or electro-chemical treatment process. Expandable graphite has all the unique characteristics of natural crystalline graphite with high temperature resistance, corrosion resistance, and self-lubricity. The expansion temperature starts at 150°C to 220°C and expansion volume can be as high as 400 times its original volume.

SUNGRAF is the most professional expandable graphite producer and now it is sole high purity expandable graphite supplier who can gurantee the quality of purity graphite.

 

INDUSTRIAL APPLICATION

 

1.Manufacturing graphite foil, graphite braided packings and other sealing products.
2.Lubricant additive.
3.Fire retardant additive in plastics and fire retardant foams for insulation

Main Features

1) Simple structure in linear type ,easy in installation and maintation.

2) Adopting advanced world famous brand components in pneumatic parts ,electric parts and operation parts.

3) High pressure double crank to control the die opening and closing.

4) Running in a high automatization and intellectualization,no pollution

5) Apply a linker to connect with the air conveyor ,which can directly inline with filling machine .

 

 

1.What is the difference between graphite and expandable graphite?
 
The graphite that is modified to a structure consisting of layers, with spacing in between each layer is called expanded graphite. This modified structure of Graphite has electrical and thermal conductivity 150 time better than the original graphite.
 
2.What is expanded graphite?
 
Expanded graphite is a modified graphite that has a layered structure with interlayer space (Fig. 7.5). The electrical conductivity of this material is graphite, but it can expand to more than 150 times.
 
3.How is expanded graphite made?
 
The graphite flakes are mixed with a highly oxidizing acid to form an intercalation compound which is expanded by applying high temperatures. The resulting expanded graphite worms are mechanically compressed into graphite foil without fillers or binders. Then the foil is ground to expanded graphite powder.
