Firefly 900 Millboard (FF900)

Note: This is a variation of Firefly Millboards.

Firefly non-asbestos / non-ceramic fiber Millboards are used in a wide variety of industrial applications for high temperature thermal insulation and gaskets. Firefly Millboards exhibit exceptional wear resistance. This, coupled with performance at temperature and ease of cutting, makes Firefly the ideal solution to all high temperature gasketing problems. In addition, Firefly Millboard has set the standard for roller cladding material, designed to meet the most stringent requirements of glass and steel producers worldwide.
