Details
Highlights
- Advanced fiber technology specifically designed for a high-temp automotive acoustic absorber
- Non-woven fibers deliver higher sound absorption performance vs. PU foam parts
- Resists temperatures of 302°F (150°C) for 336 hours or 356°F (180°C) for 48 hours
- Hydrophobic fibers resist moisture, mold and mildew
- Material does not require special handling typically associated with fiberglass
- High-performance black scrim resists fluids and chemicals
- Can be converted into shapes and configurations to fit OEM and Tier application needs
3M™ Thinsulate™ High Temperature Acoustic Absorber HT500P features a web of polyester fibers for automotive sound absorption even in high-temperature applications. It resists temps up to 356°F (180°C) for 48 hours, excellent for use inside engine compartments. A durable black scrim reinforces the web and resists chemicals and fluids. Material can be die-cut into complex shapes and configurations.
Automotive Noise Reduction at High Temperatures
Featuring advanced fiber technology, 3M™ Thinsulate™ High Temperature Acoustic Absorber HT500P is designed for durable automotive NVH reduction in high temperature environments such as automotive engine compartment applications. This material is designed and tested to withstand temperatures up to 302°F/150°C for 336 hours or 356°F/180°C for 48 hours. The internal polyester web is designed specifically to absorb vibration and help reduce unwanted noise from traveling throughout vehicles, and the black external scrim resists common engine fluids.
Properties of 3M™ Thinsulate™ Acoustic Absorber HT500P
Thinsulate High Temperature Acoustic Absorber HT500P features an overall thickness of 23 mm and a basis weight of 568 g/m2. Non irritating fiber material won’t produce dust during processing or installation and doesn’t require any special handling. The hydrophobic fiber web resists moisture and greatly reduces the chance for mold and mildew to develop over time. A high performance black scrim on one side of the fiber web is designed specifically to resist chemicals and fluids.
Highly Convertible for Design Freedom
Our 3M™ Thinsulate™ High Temperature Acoustic Absorber HT500P is easily processed by conventional techniques such as die cutting, and can be converted into a wide range of shapes and configurations to fit OEM and Tier application needs. It attaches to many substrates using conventional clips, heat staking or ultrasonic welding.
Recommended Applications:
- Automotive underhood
- Engine under covers and beauty covers
- Battery covers
- Hoodliners
- Front of dash panels
The Science Behind Noise Absorption with Thinsulate Products
All sound is transmitted through physical vibrations. Where many acoustic insulation products act as a damper or a barrier that simply block the transmission these vibrations from a source to other locations, our Thinsulate acoustic absorbers and insulation are engineered to absorb them instead. Tiny fibers are manufactured to exact diameters and assembled into a web. As physical vibrations pass through this web, it essentially tunes them to differing frequencies. This absorption process converts vibration from physical energy – which causes noise and discomfort – into heat, which dissipates quickly and quietly. The result is a quieter, smoother, more comfortable space inside the vehicle cabin, and another example of how 3M applies science to life.
