Absorbs Noise So That Passengers Ride in Comfort To make the ride in vehicles more comfortable for passengers, 3M™ Thinsulate™ Acoustic Insulation SM600L absorbs noise so that it is quieter in the interior of vehicles. Our automotive acoustic insulation is made from a unique combination of fine microfibers that absorb high frequency noise and thicker fibers that provide recovery and loft. It is compressible, lightweight, conformable and can be easily die cut, heat sealed and thermally or sonically bonded to many substrates. How Thinsulate Acoustic Insulation Works Our insulation is a unique non-woven acoustic absorber composed of polyester and polypropylene fibers. The polypropylene fibers are extremely fine, producing a high-energy absorption characteristic with low weight. The polyester fibers are added to strengthen the web, while the scrim protects and contains the fibers. Application Recommendations Our SM series of automotive sound insulation is recommended for instrument panels, parcel trays, pillars, trunk liners and wheel wells. Depending on application requirements, 3M™ Thinsulate™ Acoustic Insulation SM600L may be evaluated for use in the carpet/dashmat, door panels, headliners and other variable cavity applications. To determine suitability, consult your 3M Acoustic Solutions Technical Service Engineer. Reasons Why Automotive Manufacturers Choose 3M™ Thinsulate™ Acoustic Insulation Quieter Vehicles. Provides highly efficient acoustic absorption, particularly in middle- to high-frequency ranges. Lighter Vehicles. Thinsulate acoustic insulation products are made from lightweight polyester and polypropylene non-woven fibers. Easy to Install. Lightweight and easy to handle. Mold, Mildew and Moisture Resistant. Install just the insulation – there’s no need for an additional waterproof layer during application. Thinsulate acoustic insulation is also resistant to mildew growth, reducing the risk of offens 3M™ Thinsulate™ Acoustic Insulation MA6710 3M™ Thinsulate™ Acoustic Insulation TH4320 3M™ Thinsulate™ Acoustic Insulation AU3020 3M™ Thinsulate™ Acoustic Insulation TC2203 3M™ Thinsulate™ Acoustic Insulation AU1220 Very Light Weight for Mass Reduction  Part of our TC family of cavity filling solutions for automotive OEM, 3M™ Thinsulate™ Acoustic Insulation TC1803 has one of the highest acoustic absorption-to-weight ratios of any Thinsulate product. This very low density (8.8 kg/m3) insulation is excellent as an NVH cavity filler for applications where mass reduction is a major goal. Its internal web features thick and thin fibers and is designed specifically to absorb vibration and help reduce unwanted noise from traveling throughout vehicles. Built for Lasting Noise Absorption The internal web of the product is composed of a combination of polyester (PE) and polypropylene (PP) fibers. The PP fibers are extremely fine, allowing for high-energy absorption without adding weight. The thicker PE fibers add loft, strength and stability to the web. The lightweight reinforcing white scrim on both sides is made from 100% polypropylene non-woven fabric for durability. Properties of 3M™ Thinsulate™ Acoustic Insulation TC1803 This acoustic insulation material has a caliper of 21 mm and a basis weight of just 185 g/m2. Fibers are contained in a single scrim. Compressible and Conformable for Gap Filling Thinsulate Acoustic Insulation TC1803 is designed for excellent compressibility and recovery. This is ideal for applications where filling spaces of varying thickness is important, such as door trim panels and body side trim panels. As the insulation conforms, it completely fills even irregular spaces for extremely consistent noise absorption throughout the application. It is most effective as an NVH cavity filler. Our Thinsulate Acoustic Insulation TC1803 can be processed by conventional techniques such as die cutting. It attaches easily using ultrasonic welding, hot melt adhesive or mechanical fasteners. Recommended Applications:  Variable cavity NVH Door trim panel Door hole seals Head liners Wheel wells Trunk liners 3M™ Thinsulate™ Acoustic Insulation TC3403 3M™ Thinsulate™ Acoustic Insulation AU2020 3M™ Thinsulate™ Acoustic Insulation TAI4031AL 3M™ Sound Deadening Pad, 500 mm x 500 mm, 08840 3M™ Thinsulate™ Acoustic Insulation AU2002 3M™ Interam™ Mat Mount 2000HT 3M™ Thinsulate™ Acoustic Insulation TC3303 3M™ Interam™ Mat Mount 1650HTG 3M™ Thinsulate™ Acoustic Insulation TC2303 3M™ Thinsulate™ Acoustic Insulation AU0920 3M™ Thinsulate™ Acoustic Insulation TAI4047 3M™ Thinsulate™ Acoustic Insulation AU4002 3M™ Thinsulate™ Acoustic Insulation TAI2001 3M™ Thinsulate™ Acoustic Insulation TAI3047 3M™ Thinsulate™ Acoustic Insulation AU6002 3M™ Thinsulate™ Acoustic Insulation TAI4001 3M™ Interam™ Mat Mount 1801
