Description
Description
Bio Soluble Blanket is a body soluble fiber that utilizing a unique spinning technology and mechanical properties.
These special fibers are made from a blend of calcium, silica and magnesium which give fiber the ability to support continuous applications under high temperature conditions. Bio Soluble Blanket is flexible and competent in treating with the refractory linings, thermal insulation and metals transfer, it has been Proven superior and eco-friendly to traditional refractory ceramic fibers.
Features
