Graphite Treatments & Impregnation Services

To enhance the performance, durability, and chemical resistance of machined graphite, Graphx Tech offers a wide range of advanced treatments and impregnations tailored to demanding industrial applications:

Oxidation Reduction Treatment

Designed for oxygen-rich environments up to 1,000°F, this treatment applies a thin barrier film to both the surface and internal porosity of graphite. It significantly reduces oxidation and erosion of synthetic graphite binders.
Ideal for: Static casting, glass manufacturing, molten aluminum processing.

Phenolic Resin Impregnation

Fills graphite porosity with phenolic resin and cures to form a dense, low-porosity composite resistant to acidic and basic environments.
Ideal for: Chemical baths, heat exchangers, anodes, cathodes, and applications requiring near-zero porosity.

Wax Impregnation

Paraffin is infused into graphite porosity and cured to create a low-porosity, chemically resistant material — effective at lower temperatures.
Ideal for: Chemical processing, anodes/cathodes, and fluid applications where mild thermal resistance is acceptable.

Metal Impregnation

Graphite is impregnated with metals like copper, babbitt, or antimony to enhance mechanical properties such as wear resistance and conductivity.
Ideal for: Bushings, bearings, wear plates, and friction-reducing applications.

Graphite Purification

Reduces ash content and impurities to ultra-low levels (down to 0.05 ppm), depending on the base graphite grade.
Ideal for: Semiconductor manufacturing, crystal and quartz growth, high-purity hot zones.

CVD / SiC Coatings (Chemical Vapor Deposition)

Deposits a uniform layer of silicon carbide or other compounds, providing exceptional chemical inertness and thermal stability.
Ideal for: Semiconductor, solar, and LED production where high-purity, coated graphite components are essential.

PTFE Coatings

PTFE (Teflon) coatings are applied in powder or liquid form to enhance chemical resistance, reduce friction, and improve thermal stability across complex geometries.
Ideal for: Non-stick, chemically inert applications across various industrial sectors.
