Armil CFS offers several alternatives to traditional ceramic fiber materials. Insulfrax® and Isofrax® are low biopersistence insulation materials that meet European regulatory requirements (Directive 97/69/EC) for man-made vitreous fibers.

Insulfrax is based on calcium, magnesium, silica chemistry and is capable of continuous operation to 2012°F. Insulfrax fiber chemistry has been combined with Unifrax’s proprietary fiber spinning technology to create Insulfrax S blanket, a high temperature bio-soluble blanket with excellent thermal and mechanical properties. Insulfrax S blankets offers both low thermal conductivity and excellent resistance to thermal shock. Insulfrax S blanket exhibits no smoke generation or outgassing while in service. Insulfrax Papers, Boards, and Vacuum formed shapes are also available.

Isofrax is based on a unique patented silica-magnesia chemistry and is capable of withstanding continuous operating temperatures to 2300°F. Isofrax meets European regulatory requirements. Isofrax products exhibit low thermal conductivity, excellent thermal stability and thermal shock resistance. Blankets, Modules, Papers, And Boards are available.
