NVH stands for noise and vibration harshness. NVH materials are focused on mitigating unwanted noise and vibration sources in vehicles. NVH components and techniques are employed outside the automotive industry to reduce the noise and vibration effects in manufactured electronic products and machinery.

Impact of COVID-19 on the Automotive NVH Materials Market: Challenges and Opportunities
There are a variety of materials used in the fabrication of NVH parts.
Rubber is considered an ideal material, as it possesses high density, which facilitates easy sound absorption and noise in vehicles. It enables the even distribution of noise and vibration across the material due to its consistency.
Plastic and foam are highly preferred NVH fabrication materials. Plastic is ideal for reducing noise and vibration harness caused by impacts and bumps. It transfers sound through air and structure.
Butyl Rubber and Base Polymer: A pad-type product made from base polymer and butyl rubber is used to reduce noise. It involves aluminum foil laminated onto self-adhesive sheets. This anti-vibration pad is used at doors, roof panels, QTR, and side areas of the car body. It absorbs vibration caused by driving as well as opening and closing doors. It thus improves the car's durability with self-adhesive features in a semi-permanent manner.

Vehicle weight reduction is a major concern in the automotive industry. The lightweight vehicles save energy, and experience reduced brake and tire wear, as well as decreased emissions. Lightweight vehicles consume less energy and improve fuel economy. They help in controlling noise and vibration harnesses.
According to a study, vehicle mass reduction can decrease up to 15% fuel consumption, as well as cause comparatively 10% reduced emissions.
Numerous automotive manufacturing companies have increased the consumption of NVH material to cater to the rising demand for lightweight vehicles.
The demand for NVH materials in the automotive sector is rising due to worldwide rinsing road traction of automobiles, led by increasing urbanization, surging disposable incomes, and shifting lifestyles.
The major players operating in the industry are; Exxon Mobil Corporation, Mitsui Chemicals Inc., Huntsman Corporation, DowDuPont Inc., Borgers SE & Co. KGaA, and Covestro AG.
Therefore, the rising road traction of automobiles propels the demand for automotive NVH materials.
