Calcium Silicate Boards - Marinite A

A strong, machinable, non-asbestos inorganic panel for conveying, containing, handling and forming molten aluminum and non-ferrous metals. The hardest of the Marinite boards.

Application
Floats, spouts, stopper pins, distribution boxes, dams, baffles, filter boxes, troughs, head boxes, transition plates, hot top rings, aluminum holding, die-cast furnaces.
Characteristics
Metals do not adhere, even when cooled and solidified. Will not contaminate metals and requires no facing wash. Conveys metals with less heat loss and at a uniform temperature requiring a lower handling temperature.
