Marinite P
Marinite P structural insulation is an incombustible, self-supporting board that combines high insulating values, fire safety, and exceptionally high compressive strength in a variety of fire protection and heat processing applications.
Because of its thermal insulating values and high compressive strength, Marinite P structural insulation is especially well suited to withstand both the temperatures and pressures associated with platen press operations. It also provides durable, low maintenance insulation for large diameter pipe support systems in the power generation and process industries.
It provides an ideal backup insulation in rotary kilns in lime and cement plants, and steel ladles, torpedo cars and tundishes in steel plants. In these applications, Marinite P has withstood estimated hot face temperatures of 1700-1800°F, and has performed well where less compressive-resistant boards have failed.
In ceramics and foundry applications, Marinite P insulation can be used as a pallet to support special refractory shapes and foundry cores during oven drying. In addition, it provides an effective alternative for many of the industrial applications which previously used Transite® flat sheets.
