BNZ Materials manufactures and is a worldwide supplier of a range of specialty industrial insulations. Our calcium silicate insulation has been manufactured continuously at Billerica, Massachusetts for more than 60 years.
This board was developed to be a high temperature replacement for asbestos Transite. It offers our highest strength and electrical resistance combined with minimal shrinkage for applications up to and exceeding 1800°F. Potential applications include platen press insulation, foundry core and blow plates, induction furnace casing, electrical resistance insulation, hot glass handling and numerous others.
Marinite A and Marinite C
These boards are heat treated formulations for use in conveying, containing and forming molten aluminum and other non-ferrous metals. Applications include holding furnace linings, tips for continuous casters, transition plates, rings, plugs, baffles, troughs, spouts, floats and filter boxes.
Marinite P, Marinite I and Marinite M
Oven dried formulations of BNZ boards are used in a variety of heat insulating processes, fire protection and machined parts. Selection is commonly based on a balance between strength and insulating qualities. Examples include oven walls and linings, soldering insulation, fire doors, fire training burn buildings, cable trays, personnel protection, and as USCG-approved insulation for marine ships and off-shore rigs. Back-up insulation applications include ladles, torpedo cars and tundishes in the iron and steel industry, lime and cement plant rotary kilns, and aluminum die cast holding furnaces.
Transite HT and Transite 1000
These non-asbestos, monolithic fiber cement industrial boards are used in environments up to 1000°F where high strength is the primary concern. These fiber cement boards are used in the foundry industry for flask liners, core, drying and carry plates, and induction furnace casings. Electrical applications include busbar supports, aluminum pot insulation, and electrode arm insulators. Transite HT and Transite 1000 are also used as load bearing gasketing, spacers, supports, and machined parts for OEM applications.
