Impervious graphite,as one kind of special nonmetallic material, mainly includes soak graphite, profiling graphite and pour graphite, its thermal conductivity is higher than many metals, and has the outstanding chemical stability and thermostable, the good heat conduction and the electric conductivity, the good physics mechanical property and the workability, mainly uses in making the chemical process equipment, the heat exchange equipment, widely used in chemicals industry, pesticide, medicine, spinning and weaving, food, petroleum etc.

Equipment characteristic:

1. Corrosion proof: suitable in none-oxidized or weak oxidized strong acid, alkalis,  salt solution, organic acid, majority of organic solvents and the compound medium.

2. High thermal conductivity: its thermal conductivity is higher than many metals, only smaller than copper and the aluminum, two times than carbon steel, five times than stainless steel , occupies head of the nonmetallic material, suits manufactures each kind of heat exchange equipment.

3. Linear expansion coefficient small, thermostable, heat-resisting impact.

4. The surface not easy scaling, no pollution.

5. Machine cutting performance is good.

6. Small density, light weight.
