NATURAL GRAPHITE

Amorphous graphite is the most common form of graphite. Unfortunately, It is strongly contaminated and its structure is a transient form between amorphous carbon and crystalline graphite. The flake graphite hasn’t these defects, which is a form of natural graphite with highly ordered crystalline structure and characteristic metallic gloss. The nature of spatial structure of flake graphite results in ease breaking bonds between layers and forming a scaly structure. The consequence of this structure is high anisotropy of graphite properties. Strength and conductivity in a direction parallel to the axis of crystallite exceed several times the value in a direction vertical to that axis.

Modified, expandable flake graphite. Due to the possibility of expansion at higher temperatures, this material is used as a flame reducing agent (flame retardant) in plastics and fireproof coatings.

High purity expandable graphite with a high expansion potential level 300 ml/g. This type of graphite is designed for the production of flexible seal materials and high-efficiency gaskets for power engeenering.

Large-flake graphites with visible flake structure and specific metallic gloss. These graphites are used as component of sealing and refractory materials and in a foundry.

Fine flake graphites with medium purity, designed for foundry and metallurgical production also as modifier addition for plastics. They are an effective addition of the antistatic coatings, where they increase electric conductivity and work as a passivation agent of electrical charges.

Micropowders based on flake graphite with high purity, designed for components of graphite lubricants. Successfully are also used as modifier additives for plastics, paints and colloidal dispersions.

Amorphous graphite in a powder form, is designed to prepare powders and separating coatings in the foundry and metallurgy. It can be used in both forms: as powder or as a water dispersion form. It is an excellent high-temperature lubricant also a separator of casting models and casting moulds.

Graphite colloidal dispersion, in a semi-liquid suspension with the addition of a stabilising agents. This is a special preparation for spraying protective coatings in metal casting and for lubricating of forging moulds.
