Sound Shield Automotive Sound Deadening Mat

The Sound Shield Automotive Sound Deadening Mat uses 2mm thick high-quality butyl rubber damping layer + 0.1mm thick aluminum foil surface layer composite structure, is the most basic and most important material in automotive sound insulation noise reduction engineering. Butyl rubber layer uses imported butyl rubber raw material, damping factor above 0.25, can effectively suppress body steel plate vibration, converts vibration energy into heat energy dissipation, from source reduces resonance noise generation, especially for door, trunk, roof and other large-area steel plate positions, damping effect significant. Aluminum foil surface layer uses high-strength aluminum foil, has excellent heat reflection performance, can reflect engine and exhaust pipe heat, lowers in-car temp, while protects butyl rubber layer from high-temp aging, extends service life. Backing adhesive uses high-adhesive acrylic pressure-sensitive adhesive, initial adhesion and holding adhesion both reach industry high standards, peel and stick, construction no heating needed, hand or roller press即可 firmly stick, no falling off no glue flow, construction temp range 5°C-40°C, DIY user can self-construct. Material passed ROHS and REACH eco certification, no odor no harmful substances, after construction in-car no odor, high temp resistant 120°C, low temp resistant -40°C, adapts to in-car various temp environments. Provides universal size 46×80cm/sheet, can freely cut based on construction position, fits door, chassis, trunk, hood, roof, fender, U-slot and any position. Each damping mat weight about 0.8kg, full car sound insulation construction about needs 15-25 sheets. Passed ISO 9001 quality certification, material经过 1000h aging test and 100 high-low temp cycle test no cracking no falling off. Damping mat is the basic material for car sound insulation, recommended配合 sound absorbing cotton, sealing strip use, achieves full-band sound insulation noise reduction, can reduce in-car noise 3-6dB, significantly improves in-car quietness and audio effect.
