Pyrotek U-1 Compressible Board
Categories:	Ceramic
Material Notes:	U-1 is a high-temperature millboard that is easily cut, punched and shaped. It works well as a roll-cladding material and as compressible gasketing. A unique characteristic of the asbestos-free board is its ability to be formed to various shapes by wet molding. After drying its mechanical properties remain constant. U-1 is made from high-quality, shot free mineral wool and inert filters. It exhibits excellent flame and heat resistance with virtually no dimensional changes. It has self-cleaning properties and has no shot or abrasive elements to scratch hot glass. Available forms Boards: 1 m x 1 m Boards: 40in x 40in Available thickness 2.5 mm - 12 mm 3/32 in - 1/2 in Applications Glass lehr rolls Gaskets and seals Furnace lining Catwalk insulation Ball mill insulation High-temperature compression gasket Advantages Asbestos-free Excellent thermal stability High mechanical strength Non-abrasive Wet moldable Information provided by Pyrotek.
