Increasing Presence for Light Weight Vehicles Fuels Demand for Automotive NVH Materials

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.

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.

Additionally, foam is cut to develop form components for NVH applications. It includes roof headliners that affect sound inside the vehicle cabins. Foam sheets function effectively, as a material developed for NVH reduction, more specifically in cases of exposure to harsh conditions and chemicals.

Consumer preferences have shifted over time with the evolution from fuel economy to luxury and comfort vehicles. It increases the focus of manufacturers on NVH fabrication.

A baffle pad is a self-adhesive pad-type product. It reduces the noise in car pillars and other areas that needs to be sealed. It can be used in internal structures, including wheelhouses, waxing holes, and roof rails. Baffle pads expand and fill the empty space, by passing through the ED oven process. It offers ease in vertical application.

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.
