Marinite P, Marinite I & 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.
