Basalt Fibre
Basalt is formed by the solidify process of lava. The crystallization process forms columns with a hexagonal shape. The solidified lavas and intrusions constitute the igneous rocks. Only from this igneous rock -basalt– basaltfibers can be extracted. Basatlfibres can be used in a vareity range of industries.
Basalt fibre specific properties such as:
Stability to the influence of high temperatures and resistance to corrosive medium allows application of basalt fibre in a large variety of different areas. Such as:
• Concrete and asphalt reinforcing material; concrete covers of motor roads and airfields
• Chemical and corrosion resistant reinforcement. It several times exceeds alloyed steel in strength
• Incombustible and fireproof composites for nuclear and thermal power plants, oil processing and chemical plants
• Filters for industrial and domestic use; filters for smoke and dust emissions of industrial enterprices
Basalt Fibre rebars (for concrete reinforcement)
100% C02 footprint
Ecologically clean (made by lava from vulcans).
100% Fire proof
The temperature of application is -260° C tot 800° C
Higher strength
higher tensile strength and E- modulus
Thermal Stability
Better thermal stability
Resitance to Acids
better resistance to acids and alkalis
Water repellent
Not absorbing water through the core
The use of basalt fibre rods has a series of advantages comparedto conventional reinforcing bars:
The physical properties of basalt fibre are very attractive.
Compared with E-glass, the most common type of basalt fibre
has a higher tensile strength and E modulus, better thermal
stability, better resistance to acids and alkalis and not
absorbing water through the core of the fibre like fibreglass does.
Compared to carbon fibres, basalt is much lower in cost and
creates complete absence of conductivity and the
self-induction when exposed to electromagnetic radiation.
Reinforcement of basalt is much stronger and lighter than
steel with the same diameter. A variety of diameters are possible.
Other applications for Basalt fibres
Needle-punching material
The product can be used for the manufacturing of filters,
composites, thermal-insulating and soundproof materials.
Needle-punching material is very suitable as fire protection
of high-rise buildings, industrial projects and fire-hazardous
constructions (factories of petrochemical industry).
Basalt fibre composites applications:
• Industrial and civil engineering construction
• Fireproof protection systems of buildings and constructions
• Thermal insulation of steam pipelines and heating mains
• Machinery construction
• Automobile production
• Shipbuilding
• Aircraft industry, rocket production, space industry
• Nuclear power engineering
• Electronic industry
• Chemical industry
• Petrochemical industry
