Fiberfrax FC-25 tamping mix and Vari-Form™ castable materials provide casting mixes which can be applied in small areas such as furnace access and site doors, tube sheets, and as a refractory backup. FC-25 tamping mix is a wet mix containing Fiberfrax fibers and inorganic binders. It is poured directly from the container and tamped into place. Dry density is 20-25 pounds/cubic foot. Vari-Form is a dry mix available in two density grades of 30-40 and 50-60 pounds/cubic foot. Water is added to the dry product at the job site and mixed thoroughly. It is then simply poured and troweled into the area to be insulated. The mix sets in about 18 hours and can then be heated to operating temperature.Typical Applications- Backup insulation
