Import Car Sound Deadener — Buy in Bulk from Supplier in China

The product is a car sound deadener designed to reduce interior noise from rain, wind, road and tire contact. It combines a specially formulated butyl rubber layer with a processed aluminum foil sheet. The supplier lists three primary functions: vibration damping, noise reduction and thermal insulation. The material is advertised as flexible, adhesive and free of harmful odor. In the automotive acoustic market, butyl rubber is commonly used for its low compression set and good damping characteristics. Typical sheets of butyl‑based deadener are supplied in thicknesses between 0.3 and 1.0 mm, a density around 1.1 g cm‑3 and an acoustic attenuation of 30‑40 dB across the 100‑500 Hz band. The added aluminum foil, usually 0.02 mm thick, provides a hard surface that resists oxidation and adds modest thermal conductivity of about 0.2 W m‑1 K‑1. The adhesive backing allows a cut‑peel‑stick installation without additional fasteners, which matches the supplier’s claim of easy installation. The deadener is suitable for OEM vehicle manufacturers, aftermarket tuners and importers seeking quieter cabin environments. Buyers typically order the material in rolls or pre‑cut sheets, and the supplier indicates that the product can be installed by cutting to shape and applying directly to metal or plastic surfaces. Specific minimum order quantities, lead times and payment terms are not disclosed in the listing, so prospective purchasers should request these details from the supplier.
