Basalt Fibers - Main Advantages

• tensile strength 20-25 higher than E-glass
• tensile modulus 15-20 higher than E-glass
• higher stiffness strength in reinforced plastics

Basalt Fibers - Main Advantages

• chemical resistance in both acid alkali
  environment better than E glass
• extended temperature range (up to 580oC)
• environmental friendliness
• easy recycling of Basalt Fiber Reinforced
  Plastics (BFRP) in comparison with GFRP

Basalt fiber properties significantly outperform
E-glass and get close to specialty fibers like
S-glass, carbon, chemical resistant glass, silica
but at a lower price

Basalt Fibers - Production

• Monofilament diameter 10-21 micron
• Direct roving - 68-290 tex
• Assembled roving up to 48 creel positions
• Sizing capabilities epoxy- multicompatible,
  for wet chops, for textile processing, for
  concrete reinforcing.
• Winding/rewinding equipment mostly DS
  (Germany)
• Chopping equipment Brenner (USA)
• Twist frame in the fall 2006 - Twistech (Spain)
• Current output 1,200 MT (annual basis)
• Capacity up to 3,000 MT (annual basis) by the
  end of 2006 and 5,000 MT (annual basis) in 2007
• Ready to expand to 15,000MT/year within 18-24
  months

• Basalt fibers have complex of properties
  enabling use of basalt fibers as replacement for
  asbestos, high strength glass, silica, chemical
  resistant glass and other special fibers in many
  applications
• In a number of applications basalt fibers may be
  the best material due to unique combination of
  their physical and chemical properties
