AcoustiSorb 2 D A T A S H E E T ..Product Description & Typical Applications AcoustiSorb 2 is a medium weight flexible insulation designed for internal lining of air conditioning ducting. A continuous length as a ductliner has the advantage of reducing waste through being able to be cut to varying lengths. Other recommended uses include storage tanks, process equipment, appliance cabinets, plant rooms and acoustic baffles. o ..Physical Characteristics Nominal Thickness (mm) Dimensions...Rolls 25 & 50mm ........................Pads 25 to 100mm Nominal Density (kg/m3) 25 to 100mm 15m x 1200/1500mm & 8m x 1200/1500mm 2400 x 1200/1500mm 32 o ..Early Fire Hazard Rating When tested in accordance with AS1530 Part 3-1989 "Early Fire Hazard Properties of Materials", AcoustiSorb 2 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 2 at a mean* temperature of 20oC is 0.0357 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 2 has the following sound absorption coefficients when tested to AS1045 by the Reverberation method: Frequencies Plain 25mm Plain 50mm Perf Foil 50mm Al Foil Trilam 50mm Plain 75mm Plain 100mm 125 0.13 0.28 0.37 0.26 0.47 0.67 250 0.42 0.65 0.75 0.68 0.91 1.08 500 0.71 0.95 1.07 1.10 1.05 1.16 1000 0.89 1.06 1.08 0.92 1.02 1.11 2000 0.93 0.99 0.94 0.60 1.08 1.12 NRC 0.75 0.90 0.95 0.80 1.00 1.10 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
