Compression Molded Insulation Flange Seal for the Aerospace Industry

This compression molded insulation flange seal is manufactured in a series of steps. First, a foam insert (BMS 1-68) , molded in 2 parts, is bonded together into the designated shape. Next, fabric (D2000) is blended with a red silicone compound (BMS 1-74) using a red iron oxide ingredient which renders the component heat-retardant. The silicone and fabric combination is then hand applied around the foam insert to achieve the proper level of thickness, and then placed in a cool mold. A total of 6 different rubber coated fiberglass inserts are applied to the seal, at specified locations, to create the reinforced attachment points for the seal. The mold is then placed in the press at 320 degrees Fahrenheit (F) for 30 minutes, removed, cooled, and cleaned.

The final component shape is set by post curing the seal at 400 degrees F. The completed insulation flange seal is used extensively in engine areas of a commercial aircraft.
