High Temperature Wedge Millboard 1700 Benefits

Wedge Millboards 1700 are non-asbestos Millboards manufactured with excellent quality of high temperature mineral fibers. These Low cost, high strength, high temperature insulation Millboards are widely used as back-up insulation, as heat-shields, and as splash-guards. This is not only in the steel industry, but in many industries involving the transfer of molten metals.
