Basalt fabric is woven from high quality continuous-filament basalt fiber.
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

| 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 | ||||||
