FIBERFRAX DURABLANKET (S)

Fiberfrax Durablanket S is a premises grade product made from spun 1260 Deg. C ceramic fibers. The extra long spun fibers make one of the strongest blankets available. This coupled with its superior resilience make it particularly tough and suitable for applications involving further handling or difficult environments.

FIBERFRAX DURABLANKET (Z)

Fiberfrax Durablanket Z is a high temperature blanket made from Zirconia stabilised spun ceramic fiber. It is a highly efficient insulator with extremely low shrinage characteristics,at elevated temperatures.
