Basalt Fibre
Basalt fibre has properties that are far superior to fibreglass. For example, basalt fabric subjected to the flame of a Bunsen burner will redden and could withstand for several hours compared to a few seconds for a fibreglass fabric of the same density. Basalt products resist flame, continuous temperatures of up to 700 °C, chemicals (acids and bases), are very good acoustic and electrical ...

The many uses of Basalt include the following
· 1. Textile appliions for fire protection Basalt does not melt nor shrink in the flame and, when not mechanically stressed, keeps its geometric integrity. When coming to heat resistance, Basalt is exceptionally suited to block fire. Basalt products resist the open flame. Basalt melts at ca. 1450 C. A fabric made of Basalt, with a [.]
