Fiberfrax^® Moist Pak‑D^®

Fiberfrax^® Moist Pak-D^® is a moldable and formable blanket insulation containing an inorganic wet binder. It dries upon firing to a hard shape having a dry density of 12-18 pounds/cubic foot. Moist Pak-D insulation possesses excellent thermal insulating properties and effectively resists hot gas velocities well in excess of 100 feet/second.

Moist Pak-D insulation is used primarily as a surface layer over Fiberfrax blanket linings in hot gas erosion applications. It is also used to protect alloy hardware exposed to high temperatures, as a durable insulating cover for exhaust lines, around burner assemblies, and wherever a formable blanket is needed to provide strength and hot gas erosion resistance.

Moist Pak-D is ideal for insulation of complex shapes and for service under conditions of high hot gas velocities. The material is packaged in a clear polyethylene bag to retain the wet binder during shipment and storage.
