Natural crystalline Graphite, fine grains with different carbon concentrations and an average particle size less than 150 microns
The Grafine product line is a crystalline natural graphite with an average particle size smaller than 150 microns (100 mesh ASTM) and carbon content ranging from 72.0% to 99.9%.
It is characterised by the structural preservation of the crystal lattice, without mechanical stress in mills, having in a concentration from fine particles obtained by the use of modern techniques of particle size classification.
The Grafine line is the right solution for:
- Magnesia-Carbon Refractories;
- Monolithic refractories;
- Alumina-carbon Refractories;
- Brake Pads and Shoes;
- Sintered parts;
- Friction Coatings;
- Electric Brushes;
- Release agents;
- Special paints;
- Clutches.
