Fiberfrax & Durablankets are a family of lightweight needled blankets manufactured
from Fiberfrax® refractory ceramic fibres and
provide effective solutions to a wide spectrum
of thermal management problems.
Utilizing our proprietary high output blowing and
spinning techniques these products offer superior
insulating performance, flexibility and resilience.
Fiberfrax Durablanket products are unaffected by
most chemicals (except hydrofluoric & phosphoric
acids and concentrated alkalis). Thermal and
physical properties are retained after drying
following wetting by oil, steam or water.
Fiberfrax Durablanket products are completely
inorganic, so there are no fumes when heating for
the first time. Available in a variety of chemistry,
density and thickness combinations, the Fiberfrax
Durablanket range is one of the most versatile
available to the market today.
