The basalts are hard, dense fine-grained rocks of very dark color- green or black, composed mainly of plagioclase and pyroxene. Basalt can be made into fine, superfine, and ultra-fine fibers. Basalt fibers are considered superior to other fibers in terms of thermal stability, heat and sound insulation properties, vibration resistance, and durability. They offer the prospect of a completely new range of composite materials and products.
Characteristics of Basalt Fibers

• High tensile strength
• Alkali resistance
• 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
Cut fibers are coated with a sizing treatment, which makes them highly compatible with epoxy and phenolic resins and have a typical purity of 99.8%

Typical Applications

Basalt is used as a crushed stone or concrete reinforcement aggregate. It is used as railroad ballast, floor tiles, acid-resistant equipment for heavy industrial use, basalt plastic pipers, and as a reinforcement for composites, polyester/epoxy resins, and plastics. Basalt laminate is used as a protective coating.
Other applications of basalt include Rockwool, basalt fiber roofing felt (ruberoid), the production of high-quality textile fibers, friction materials such as brake pads and linings, the manufacture of basalt mat/felt, high-temperature insulation application and passive fire protection materials, and high-performance automotive muffler filler

Packaging Options

Jars, pails, drums, multi-ply paper bags, bulk bags, and fiberboard containers



Sustainable Qualities

Basalt is a volcanic rock that is highly sustainable due to its abundance in nature and its long-lasting durability. It is a naturally occurring material that does not require a lot of energy or resources to extract, making it an environmentally friendly choice. Basalt is also highly resistant to weathering and erosion, making it an excellent construction material, particularly in harsh outdoor environments. Its durability also means it has a long lifespan, reducing the need for replacements and further contributing to its sustainability.

In addition to its sustainability, Basalt contributes to a circular economy as it can be recycled and repurposed for various applications. For example, Basalt fibers can be used as a reinforcement material in composite materials, or as a replacement for traditional building materials like steel or concrete. Using recycled Basalt can reduce the demand for virgin materials and minimize waste, further contributing to a circular economy.
