Interface Performance Materials' millboard materials are strong, thin, dense boards with excellent insulating characteristics. They are made from ceramic fiber, clay, inert fillers and a small amount of organic and/or inorganic binders for increased handling strength. Interface Performance Materials' millboard contains no asbestos and can be easily substituted for asbestos millboards in a variety of applications up to 2,300°F.
The high density and excellent compressive strength allow it to be used in abusive environments as refractory backup and personnel protection, and it will withstand contact with molten metals. Millboards are available for steel, glass and aluminum manufacturing — plus other applications requiring high temperature performance. The boards exhibit good dielectric strength and can be die-cut for gasket applications.
