Bio Soluble Fibre Technical Information
Bio soluble textile products consist of calcium magnesium silicate fibre rated to 1000°C in optimum conditions blended with a small quantity of organic fibres that decompose from about 200°C. In order to ensure that strength is maintained at high temperatures, the bio soluble yarns are reinforced with either AISI 304 grade stainless steel wire (1000°C) or E glass (550°C) filaments. Bio soluble fibres, as the name suggest, were introduced as a harmless alternative replacement for refractory ceramic fibre. However, given the high degree of shrinkage due to burn off organic content at low temperatures, they are considered inferior to silica and BELCOTEX® 110 fibre textiles. They are, however, more economical.
Bio soluble fibre has the following key characteristics for thermal applications:
- High temperature stability.
- Excellent thermal shock resistance.
- Good dimensional stability.
- Low density.
- Low thermal conductivity.
- Incombustible but only after decomposition of organic fibre.
- Good flexibility.
- Good resistance to chemical agents.
- High mechanical strength.
- High resistance to abrasion.
- Bio soluble fibre textile products do not contain any ceramic or asbestos fibre.
