Insulfrax® Thermal Insulation

Alkaline Earth Silicate (AES)- low bio-persistence fibers.  Temperature Grade: 1260°C (2300°F)

Insulfrax® thermal insulation products are based on a calcium, magnesium, silicate chemistry which produces products capable of withstanding continuous operating temperatures up to 1200°C (2012° F). Insulfrax products are designed to have enhanced in-vitro solubility characteristics which enable Insulfrax products to meet European regulatory requirements (Directive 97/69/EC) for man-made vitreous fibers.

Insulfrax® Fiber is a man-made vitreous fiber based on a calcium, magnesium, silicate composition. A high fiber index (low percentage of unfiberized particles) provides the excellent thermal performance associated with traditional fibrous insulating materials. This fiber is the feedstock used to manufacture the Insulfrax product line, and it is ideally suited for conversion to boards, coatings and vacuum cast shapes. Insulfrax Fiber was developed for the temperature range of extending from cryogenic levels through 1200°C (2012°F).

A PARTIAL LIST OF TYPICAL APPLICATIONS FOR INSULFRAX FIBER IS PROVIDED BELOW:

  • Expansion joint packing
  • Refractory construction
  • Conversion to vacuum cast tap out cones, precast molten metal dustribution shapes, high-temperature boards, fireplace logs
  • Tube seal packing
  • Manufacture of cements, moldables and coatings
  • High-temperature papers and felts
  • Specialized vacuum cast shapes
