In Lo-Con felt, this resin has been precured to produce a semi-flexible rolled sheet available in different densities and thicknesses. The binders in Duraset have been left uncured so they can be molded under heat and pressure to retain a complex shape after processing.
Fiberfrax ceramic fiber felts provide unique advantages in solving thermal management problems. These advantages include:
