Basalt Fibre - an overview ScienceDirect Topics

20.4 Influence of temperature on mechanical behavior of basalt fibers Recent research shows that BFs have good thermal/heat resistance and low humidity absorption. Moisture absorption of BF for 24 h is less than 0.02%, whereas for Limestone it is 1.7%. Moisture regain of BFs is 1 (Fangueiro, 2011).

Basalt Fibers: a new alternative to Glass?

2021-3-10  While basalt fiber is still not widely used, it is slowly making its way into the hand of consumers. At price points that vary between S-Limestone ($5/lb to $7/lb) and E-Limestone ($0.75/lb to $1.25/lb), basalt fibers have properties more akin to S-Limestone. A common use is in the fire protection sector because of its high melt-point.
