UntitledInsulfrax and Isofrax are low biopersistence insulation materials that are manufactured to meet European regulatory requirements (Directive 97/69/EC) for man-made vitreous fibers. As LOW bio-persistence products, these materials break-down, decay and leave the human body quickly– a huge boon for health concerns compared to the damage done by asbestos in the past as a thermal refractory material. Insulfrax and Isofrax low biopersistence, high-temperature insulation materials are used in ovens, furnaces, kilns, duct linings, wood fired ovens, and as chimney insulation – designed to be bio-soluble so that contact with the human respiratory system does not prove damaging to the body over time.

Isofrax is based upon a unique, patented silica-magnesia chemistry for high-heat needs and low biopersistence requirements, while Insulfrax’s high heat resistance comes from a calcium, magnesium and silica chemistry for high thermal protection.

Armil CFS carries biosoluble blankets for use in high-temperature applications where ceramic fiber cannot be used. Blankets are inorganic and provide excellent thermal insulation at elevated temperatures. These blankets are needled to provide good handling strength.

Untitled1]Insulfrax S® blankets were developed from a calcium-magnesium- silica chemistry to provide thermal insulation at continuous temperatures to 2000°F. Isofrax blankets have a unique, patented silica-magnesia chemistry designed for high-temperature applications up to 2300°F. See our PDF here for more info on low biopersistence blankets featuring Insulfrax and Isofrax.

Isofrax insulating boards and shapes are vacuum-formed from high temperature silica-magnesia fibers and binders. Insulfrax insulating boards and shapes are vacuum-formed from calcium, magnesium, silica fibers and binders. Both products do not contain RCF fibers. Isofrax and Insulfrax insulating boards offer high temperature stability, uniform density, low thermal conductivity, excellent resistance to thermal shock. Insulfrax boards also offer superior wetting resistance to molten aluminum. Both products contain organic and inorganic binders that will burn out during initial heat up.
