{"product_id":"calming-automotive-sound-deadening-damping-insulation-cotton","title":"Calming Automotive Sound Deadening Damping Insulation Cotton","description":"\u003cp\u003eThe Calming Automotive Sound Deadening Damping Insulation Cotton uses butyl rubber damping layer + aluminum foil reflective layer + polyester fiber sound absorbing cotton three-layer composite structure, is the core material for automotive sound insulation noise reduction engineering. Butyl rubber damping layer thickness 2mm, has excellent damping performance, can effectively suppress body steel plate vibration, reduces resonance noise, while has good sealing and waterproof; aluminum foil reflective layer can reflect engine and exhaust pipe heat, lowers in-car temp, while protects butyl rubber layer from high-temp aging; polyester fiber sound absorbing cotton thickness 10mm, porosity 95%, can effectively absorb mid-high frequency noise, with damping mat use achieves full-band sound insulation noise reduction. Backing adhesive uses high-adhesive acrylic pressure-sensitive adhesive, peel and stick, strong adhesion, no falling off no glue flow, construction no heating needed, hand press即可 firmly stick, DIY user can self-construct. Material uses eco-friendly butyl rubber and polyester fiber, passed ROHS and REACH eco certification, no odor no harmful substances, after construction in-car no odor, high temp resistant 120°C, adapts to door, chassis, trunk, hood and other high-temp environments. Provides universal size 50×80cm\/sheet, can freely cut based on construction position, fits door, chassis, trunk, hood, roof, fender and any position, also can customize vehicle-specific cut size. Damping mat and sound absorbing cotton dual-layer structure, damping mat sticks on steel plate suppresses vibration, sound absorbing cotton sticks on damping mat absorbs noise, dual-layer cooperation can reduce in-car noise 5-8dB, significantly improves in-car quietness and audio effect. Passed ISO 9001 quality certification, material经过 1000h aging test no cracking no falling off. Provides damping mat, sound absorbing cotton, sealing strip, wheel arch liner and other full series sound insulation materials, can combine purchase based on needs.\u003c\/p\u003e","brand":"Beijing Calming Changtu Trading Center","offers":[{"title":"Default Title","offer_id":47510534422716,"sku":"gov-lx-381","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0791\/7797\/3948\/files\/381.jpg?v=1789696442","url":"https:\/\/yasnautoservice.com\/products\/calming-automotive-sound-deadening-damping-insulation-cotton","provider":"Yasn Autoservice","version":"1.0","type":"link"}
