Marinite A
A strong, machinable, non-asbestos, inorganic board insulation for conveying, containing, handling and forming molten aluminum and other non-ferrous metals. The material is rated for up to 1500º F and has a density of 65 pcf.
Marinite A is a strong, machinable, non-asbestos, inorganic board insulation for conveying, containing, handling, and forming molten aluminum and other non-ferrous metals.
Marinite 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 A Advantages:
These unique thermal insulating sheets have many advantages—metals do not adhere to it, even when they cool and solidify.
It requires no foundry facing wash and will not lead to contamination of the metals. Molten metals convey with less heat loss, at a more uniform temperature and therefore can be handled at a lower temperature.
Marinite A Applications:
Potential applications for Marinite A include floats, spouts, stopper pins, distribution boxes, dams, baffles, filter boxes, troughs, and head boxes.
Marinite A is perfect for industrial oven insulation, press platen insulation, glass manufacturing, kiln insulation, high temp insulation, induction furnaces, crucible insulation, molten aluminum insulation, bushings, washers, spacers, covers, and tops.
