The ability of the basalt fiber to accept sizing is good. This is known as ‘wetout’.

• High tensile strength
• Alkali resistant
• High thermal conductivity
• No carcinogenic risk or other health hazards
• Completely inert with no environmental risks
• Resistant to acids and aggressive chemicals
• High E modulus resulting in excellent specific tenacity, three times that of steel fiber
• Good fatigue resistance
• Electro-magnetic resistant

Typical uses for chopped fiber strands:

• Basalt is the best reinforcement for concrete due to its tensile strength and natural resistance
to deterioration from alkali
• Reinforcement for composites, polyester/epoxy resins and plastics as used
in automotive body panels, boat hulls and pultruded products, etc.
• Friction materials such as brake pads and linings
• Manufacture of basalt mat/felt
• High-temperature insulation applications
• Passive fire protection materials
• Filler for gypsum and sheetrock board requiring increased ‘burn-thru’ capability,
to meet building regulations
• High-performance automotive muffler filler
