Description
Basalt fiber woven fabric is a material made from extremely fine basalt fiber yarn which is composed of the minerals plagioclasepyroxene, and olivine. It is similar to fiberglass, having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber. The high tensile strength and excellent acid and alkali resistance, along with the non-combustible,non-magnetic and non-conductive characteristics make it suitable for a wide range of applications such as automotive, aviation, construction, electromagnetic shields, high temperature seals and curtains.

Basalt Fabrics Features
1) Good adhesion characteristics for coatings
2) Non-combustible and fire-resistant
3) Excellent tensile strength
4) Maintains integrity at temperatures up to 1800F/982C
5) Resistant to electromagnetic radiation

Basalt Fabrics applications
1) Fire curtains, fire blanket, insulation cover
2) Filtration material for industrial emission stacks and bag-houses
3) Roof protection from fire devastation
4) Reinforcement in composites
5) Electromagnetic shields

THERMAL PROPERTIES
Melting Range: 1460-1500°C
Crystalization temperature: 250°C
Sintering Teperature: 1050°C
Thermal Conductivity, w/(m-K) 0.031-0.038


THERMAL OPERATION RANGE 
Thermal load duration Temperature range
Permanent From -260 up to +400 °C
(1) Stage 1: amorphous fiber with sizing on the fiber surface Up to +200 °C
(2) Stage 2: burning of sizing (10-15 minutes), amorphous fiber From +200 up to +350 °C
(3) Stage 3: amorphous fiber without sizing on the fiber surface From +350 up to +400 °C
Short term (few minutes) From +400 up to +850 °C
(4) Stage 4: transition of FeO into Fe2O3 and beginning of crystalliza From +400 up to +850 °C
Short term (few seconds) From +850 up to +1250 °C
(5) Stage 5: all the Fe2O3 is in crystal form, the material is extremely brittle, its mechanical properties are extremely poor but without stress and vibration it
continues working as thermo insulation pretty good
From +850 up to +1050 °C
(6) Stage 6: sintering temperature From +1050 up to +1250 °C
