Insulfrax® S Blanket

Insulfrax® S fiber chemistry has been combined with Unifrax’s proprietary fiber spinning technology to create a specialty high-temperature blanket with superior thermal and mechanical properties.

Insulfrax® S Blanket is a flexible, strong, lightweight, needled blanket produced from Insulfrax® Fiber. Mechanical needling of the spun Insulfrax® fibers eliminates the need for binders in the product’s manufacture and results in a product with high tensile strength. Since Insulfrax® S Blanket is completely inorganic, the product exhibits no smoke generation or outgassing in service. Insulfrax® S Blanket combines low thermal conductivity with excellent resistance to thermal shock. Note that high humidity and wetting with water prior to service has little effect on Insulfrax® S Blanket.
