Noise Vibration and Harshness (NVH)

Reimagining the quiet ride

Reduce automotive NVH with Dow materials for manufacturers. The world can be chaotic and full of noise, but that doesn’t mean your vehicle has to be. Wind, roads, bumps from suspension, engine vibrations and other sources of NVH can be controlled with holistic, tailor-made sound dampening solutions - as your partner, we can help you drive innovation and performance for quieter, more comfortable journeys.

From polyurethane foams and polyolefin elastomers and resins to liquid applied coating materials, our acoustics product portfolio and unique NVH testing and analysis capabilities are sure to help your project create some buzz without making any noise.

Liquid Applied Sound Damping (LASD)

We understand the pressure to innovate and bring mobility to market faster than ever. With our ACOUSTICRYL™ acrylic liquid applied sound damping (LASD) coating technologies, a one-step spray application process makes it simple: faster assembly in safer, healthier work environments, reduced costs and waste, lower weight for better fuel economy, and to top it all off, the ability to be more versatile and flexible in design, no matter the application.

ACOUSTICRYL™

Designed for the use in high-performing sprayable waterborne sound damping coatings, this unique technology can be used in passenger cars, buses, trucks, rail and more, enabling outstanding acoustic damping compared to alternatives.

Polyurethane foams

Polyurethane foams, like BETAFOAM™ and Flex Foam Systems, provide another innovative alternative to traditional sound damping technologies across the mobility space, from airplanes to passenger vehicles. Our foam solutions fill cavities to provide structural support while minimizing costs and improving fuel efficiency through reduced weight. Polyurethane foams are also advancing circularity with solutions like SPECFLEX™ C.
