AcoustiSorb 3 D A T A S H E E T ..Product Description & Typical Applications AcoustiSorb 3 is a medium / heavyweight insulation designed as an optimal product for the internal lining of air conditioning ducting. Other recommended uses include storage tanks, process equipment, appliance cabinets, plant rooms and acoustic baffles. o ..Physical Characteristics Nominal Thickness (mm) Pad Dimensions 25 & 50mm Nominal Density (kg/m3) 25 to 50mm 2400 x 1200 / 1500mm 48 o ..Early Fire Hazard Rating When tested in accordance with AS1530 Part 3-1989 "Early Fire Hazard Properties of Materials", Plain AcoustiSorb 3 plain and faced meets the AS1668 requirements of spread of flame 0, and smoke developed no greater than 3 for the internal lining of ductwork. o ..Thermal Conductivity The thermal conductivity of AcoustiSorb 3 at a mean* temperature of 20oC is 0.0335 W/mK when tested in accordance with ASTM C518. Values of thermal conductivity may be obtained from the following graph. *Mean Temperature = T1 +T2 divided by 2, where: T1 = temperature of the hot side of insulation (oC) T2 = temperature of the cool side of insulation (oC) .. Acoustic Performance AcoustiSorb 3 has the following sound absorption coefficients when tested to AS1045 by the Reverberation method: Frequencies Plain 25mm Perf Foil 50mm 125 0.40 0.46 250 0.70 0.78 500 0.91 1.05 1000 0.95 1.06 2000 0.94 0.95 NRC 0.85 0.90 o ..Moisture Absorption When tested in an atmosphere of 65% relative humidity at 20oC in accordance with British Standard 2972-1975, the moisture content of Tontine products are less than 0.1% by volume. o
