AcoustiSorb 1 D A T A S H E E T ..Product Description & Typical Applications AcoustiSorb 1 is a lightweight flexible insulation blanket designed for external lagging of industrial equipment and appliances. It is used for applications such as air conditioning ductwork - internally and externally. As a continous length it has the advantage of reducing waste through being able to be cut to varying lengths. For hot water tanks it is sufficienly flexible to wrap around sharp angles and small radii with sufficient compressive strength to maintain thickness. o ..Physical Characteristics Nominal Thickness (mm) Roll Dimensions (mm) Nominal Density (kg/m3) 25 15000 x 1200 22 50 15000 x 1200 22 o ..Early Fire Hazard Rating When tested in accordance with AS1530 Part 3-1989 "Early Fire Hazard Properties of Materials", Plain AcoustiSorb 1 exhibits the following characteristics: Ignitability Index Spread of Flame Index Heat Evolved Index Smoke Evolved Index 0 0 0 0-1 Tests were conducted by AWTA o ..Thermal Conductivity The thermal conductivity of AcoustiSorb 1 at a mean* temperature of 20oC is 0.038 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 1 has the following sound absorption coefficients when tested to AS1045 by the Reverberation method: Frequencies Plain 25mm Plain 50mm 125 0.12 0.28 250 0.39 0.60 500 0.65 0.83 1000 0.76 0.91 2000 0.83 0.91 NRC 0.65 0.80 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
