M. H. DETRICK COMPANY TECHNICAL DATA INSULATION DIVISION CLASS 17.7 PACE 1 DATE Feb. 1, 1964 DETRICK LOOSE AND GRANULATED INSULATING WOOLS For Temperatures Up To 1600 F. Detrick Insulating Wools are light weight, efficient spun insulating materials furnished in two forms, loose and granulated. They are manufactured from selected materials which are melted in a cupola and spun while in a molten state into light resilient fibers of extremely small diameter. Detrick Wools have exceptionally low thermal conductivity due to their light, fluffy struc ture which contains countless dead air cells. They do not readily absorb moisture and are unaffected by atmospheric conditions encountered in typi cal high or low temperature uses and are fireproof and chemically stable. USES Detrick Loose Wool is composed of long, fibered wool as originally process ed. It is installed by hand-packing to fill irregular voids in heated equipment for packing of joints, furnaces, ovens, boiler walls, and similar purposes where bulk'insulations are required. Fed. Spec. HH-I-521, Type II. Detrick Granulated Wool composed of mineral wool pellets, designed to be installed either by hand-packing, pouring, or pneumatic methods. It can be compressed to various densities, but usually is packed at about 9 lbs. per cubic foot. Standard Granulated Wool is processed to an approximate size of minus 1" plus 3/4". Detrick Granulated Wool is covered by Federal Spec ification HH-I-521 Type III. THERMAL CONDUCTIVITY Typical thermal performances of loose and granulated wools at densities of 8 to 10 lbs. are tabulated below: MEAN TEMP. 50 F 100 F 150 F 200 F K .26 Btu . 28 Btu .31 Btu . 34 Btu MEAN TEMP. 250 F 300 F 350 F 400 F K .38 Btu .42 Btu .47 Btu .53 Btu PACKAGING Packed in Kraft Paper Bags at approximately 3 cu. ft. per bag. For ship ping purposes loose wool weighs approximately 30 lbs. per bag. Granula ted wool weighs approximately 35 lbs. per bag. tttiffi //r in * (tinif0+
