Insulfrax® Textiles

The Insulfrax® woven textile product family is composed of Insulfrax cloth, tape, cord, specialty rope, and braid products. 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.  Insulfrax Fiber was developed for the temperature range of extending from cryogenic levels through 1100°C (2012°F). The wide operating temperature range combined with superior wetting resistance to molten aluminum alloys makes this product ideal for applications in the aluminum industry.

Insulfrax textiles have excellent resistance to thermal shock, corrosive attack and breakdown due to mechanical vibration and stress. They also exhibit excellent chemical stability, resisting attack from most corrosive agents.
