What is NVH foam?

There are several functions that foams and NVH materials perform in the heavy-duty trucks and commercial vehicles of today. Reducing noise, vibration, and harshness (NVH) are the most obvious. Vehicle foams stiffen the body structure and help control twisting and flexing of the vehicle.

What causes NVH?

What causes NVH? Noise, vibration and harshness are caused by the car’s mechanical and electrical systems, as well as the car’s interaction with road surfaces and its passage through the air. The main sources of NVH in a car are its engine, drivetrain and tyres, as well as the sound of airflow along its body.

What is Vehicle NVH?

NVH is a term used to describe car noise, vibration and harshness that result in varying degrees of dissatisfaction.

What NVH stand for?

Vibration, and Harshness
NVH, which deteriorates the ride comfort of vehicles, stands for Noise (squeal), Vibration, and Harshness (vibrations generated by irregularities of road-surfaces).

Which is better for NVH betafoam or baffle?

Our BETAFOAM™ products offer superior NVH reduction in electric and internal combustion engine vehicles compared to baffle technology. These two-component polyurethane foams adhere to a variety of treated surfaces.

What are the Dow polyurethane additives used for?

Dow’s VORASURF™ polyurethane additives help meet a variety of needs across a wide range of applications – from footwear to mattresses, automotive interiors to spray foam insulation used in refrigerators and construction.

What does betafoam open and closed cavity filling foam do?

BETAFOAM™ acoustic open and closed cell cavity filling foams offer superior noise, vibration, and harshness (NVH) reduction in internal combustion engine (ICE) and electrical vehicles (EV). These two-component polyurethane foams serve as a cavity-sealing and blocking foam.

How is betafoam used in the automotive industry?

Our acoustic material scientists work with automotive OEM’s and tier suppliers to develop optimal acoustic treatments for their vehicles or applications using: Whether it’s reducing airborne noise in electric vehicles or absorbing vibrations from internal combustion engines, BETAFOAM™ products can help with your automotive and transportation needs.
