Insulfrax S Blanket

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

Insulfrax® S Blanket was developed from a calcium, magnesium, silicate chemistry to provide thermal insulation at continuous operating temperatures up to 2012°F (1100°C). It meets European regulatory requirement (Directive 9769EC). 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.

A series of green dots on the surface of the blanket make identification, tracking and inspection of Insulfrax® S Blanket simple on the job site or in the fabrication shop. Insulfrax® S Blanket is classified by Underwriters Laboratories (UL), per UL 723 (ASTM E-84). Flame Spread Rating = 0, Smoke Developed Rating = 0. High tensile strength and excellent thermal properties combine to make Insulfrax® S Blanket the product of choice for a wide range of applications in a number of industries.

Insulfrax® S Blanket is used in a wide range of applications including refractory linings, thermal insulation, appliances, and molten metals transfer.
