Acoustic Insulation Media

acoustic Insulation is a lightweight ,high loft,high performance synthetic fibrous insulation material,designed to provide excellent acoustical and thermal protection.Comprised of polyester staplefibers and polypropylene,it can be processed with a spunbond scrim as well as two-side ginning to enhance strength,reinforce sound-insulated effect and protect fiber.Advantages:1)Completely recyclable.2)Non-linting,high loft for excellent acoustical absorption at low weight .3)Hydrophobic-prevents build-up of weight and odors.4)Compatible weith virtually all attachement methods including ultrasonic welding ,heating staking and gluning.5)Does not support fungi or bacterial growth.6)The high loft microfibers efficiently dissipate acoustic energy at a very low mass.Application:This kind of product is designed for acoustical application under senior noisy environment,specially automobile and high-speed railway,including doors liftgates,instrument panels,pillars,package trays truk liners ,dashmats,headliners areas. product codeUN-400SBUN-300SBUN-200SB Test Method and other notesItems Basic weight (g/m2)37531523025g/m2 Includes 25gsm PP spunbond scrim Thickness(mm)2119170.002Psi(14g/dm2) Moisture regain(%)0.40.40.4GB/T 9995-1997 (JIS L 3203) Heat Resistane Sound absorption was kept Sound absorption was kept Sound absorption was keptat 120 1000hours Tensile Strength(N)MD:45 CD:32MD:43 CD:31MD:41 CD:30width:50mm length:300mm Tensile Speed:200mm/minFlammabilityGB 8410-94 (FMVSS No302)GB 8410-94 (FMVSS No302)GB 8410-94 (FMVSS No302)GB 8410-94(FMVSS No302)Composition%PP:65 PET:35PP:65 PET:35PP:65 PET:35Excludes scrimPP 100%based on a large quantity of usage in aotomobile and household, Baiso series of acoustic insulation materials provide muteenvir
