{"product_id":"acoustic-insulation","title":"Acoustic Insulation","description":"The 3M Thinsulate SM200L is an advanced automotive acoustic insulation engineered to create a quieter and more comfortable vehicle interior by absorbing sound. It utilizes a unique non-woven construction featuring fine microfibers for high-frequency noise absorption and thicker polyester fibers for recovery and loft. This design delivers superior acoustic absorption per unit weight compared to many competitive products, helping manufacturers meet mass reduction goals.\n\nConstructed from a blend of polyester and polypropylene fibers, the SM200L is lightweight and offers excellent acoustic performance. Its hydrophobic nature ensures resistance to moisture, mold, and mildew, eliminating the need for an additional waterproof layer and preventing odors. The material is also FMVSS 302 certified, meeting federal motor vehicle safety standards.\n\nInstallation is straightforward due to its compressibility, conformability, and ease of handling compared to traditional materials like fiberglass or felt. The SM200L can be die-cut, heat-sealed, and bonded using various methods, including ultrasonic welding, double-sided tape, or mechanical clips. Its properties include a 13 mm caliper, a basis weight of 242 gm\/m², and a single black scrim for fiber containment.\n\nRecommended applications for the 3M Thinsulate SM200L include instrument panels, parcel trays, pillars, trunk liners, and wheel wells. It can also be evaluated for use in door panels, headliners, and other cavity applications. For precise application requirements, consulting a 3M Acoustic Solutions Technical Service Engineer is advised.","brand":"3M Thinsulate","offers":[{"title":"Default Title","offer_id":52686705295672,"sku":"SM200L","price":40.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660670646.jpg?v=1784876056","url":"https:\/\/store.motormia.co\/products\/acoustic-insulation","provider":"MOTORMIA","version":"1.0","type":"link"}
