Kamenny Vek

Advanced basalt fiber

Kamenny Vek Company is the world’s leading manufacturer of continuous basalt fiber that is produced and sold on the market under the registered trademark Basfiber®.

Basfiber® is close to and sometimes outperforms high strength glass and other specialty fibers but beats them price wise.

Basfiber®: advantages

Basfiber® advantages over regular glass fiber (Е-glass):

  • 20-25% higher tensile strength
  • 10-15% higher tensile modulus
  • 150°C higher melting point and operating temperatures range
  • Significantly better resistance to acids and corrosion
  • Better alkali resistance
  • Environmental friendliness
  • Attractive Golden-Brown color

Basfiber®: production

Basfiber®: production

Basalt fiber offered by different manufacturers is produced from basalt rock of different chemical compositions, and various technologies are used for its production. This means that the properties of basalt fiber can significantly differ depending on the manufacturer.

Kamenny Vek produces basalt fiber at two plants, in Dubna and in Kimry. We use large-sized bushings for a full-scale production of high quality, inexpensive 1200-, 2000- and 2400-tex single-end roving. That is technically impossible for the technology of fiber production at single- or two-module furnaces, used by all other manufacturers of basalt fiber in the world.
