Marinite P

The marinite P has a good resistance to compression and bending. It is ideal for making freestanding panels, and is also used for applications requiring minimum heat distortion.


Principal applications : oven walls and linings, welding insulation, fire doors, fire training burn buildings, cable trays, personnel protection, and as insulation for marine ships and off-shore rigs.

Back-up insulation applications : ladles, torpedo cars and tundishes in the iron and steel industry, lime and cement plant rotary kilns, and aluminium die cast holding furnaces.
