Material Notes:

440 paper is a low-cost, high-strength composite paper made from a combination of ceramic fiber, inert fillers, and reinforcing fiberglass. The fiberglass gives added strength to the 440 paper at operating temperatures between 450 and 1300°F. This product is formulated with a fire retardant smoke suppressant reducing the effects of the organic binder burnout.Information Provided by Unifrax I LLC
