Fiberfrax Paper FT, DS., H
Fiberfrax papers are manufactured from Fiberfrax refractory ceramic fibres, blended with specially selected organic binders to produce flexible papers with exceptional properties. Advanced manufacturing techniques provide a highly uniform structure, enhanced by low thermal conductivity, good adhesion and a smooth surface. Fiberfrax papers are available in various thicknesses and roll sizes.
