Basalt is the most common volcanic rock type on earth, being a key component of oceanic crust as well as the principal volcanic rock in many mid-oceanic islands. Basalt fibers consisting of filaments, continuously extruded from the high temperature melt of carefully selected basalt stones with a diameter of 10 µm and higher, are well above the limit of 5 µm for being respirable.
Basalt fibers products demonstrate following properties: Natural, low ecological footprint. Unique fire and heat performance. Excellent mechanical properties. Great chemical resistance
