Environment Soluble Fiber Board is manufactured of alkaline magnesium silicate fiber and refractory fillers and organic and inorganic binders. And diisplay high temperature characteristics required to act as an alternative to RCF whilst having similar biopersistence to other exonerated fibers. Our soluble fiber  boards can be cut with a hacksaw blade allowing precise shapes to be made and can be used in direct contact with flame. It features very low thermal conductivityhas a low heat storage capacity and has good thermal shock resistance allowing it to be used in applications where large variations in temperature occur.This product also does not react with Alumina based bricks when applied in the range of the typical use temperature. Soluble  fiber  boards are available in a number of different grades:

900 ℃up to 1000 ℃
