Marinite® Calcium Silicate Boards

Marinite® C, A, AHP, I, M, and P are non-asbestos calcium silicate structural insulators that combine high strength and excellent thermal insulating characteristics for use in a variety of heat processing, fire protection, and electrical resistance applications.
  • Thermal Shock Resistance and Stability
  • Consistently Low Thermal Conductivity
  • High Structural Strength at Elevated Temperatures
  • Incombustible
  • Easily Machined
  • Insoluble in Water and Non-Corroding
Marinite® A, Marinite® AHP and Marinite® C are boards that are heat treated formulations for use in conveying, containing and forming molten aluminium and other non-ferrous metals.

Marinite® P, Marinite® I and Marinite® M are oven dried formulations and 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.
