Excessive heat generated by engine and exhaust systems in a vehicle can damage vehicle components and bodywork, but automotive heat shields prevent them from being getting burst out. Heat shields can improve the engine performance by reducing the temperature. Aluminium is the key raw material used in heat shield production.
The global automotive heat shield market, by value, is projected to grow at a CAGR of 9.7 % to reach US $25.1 Bn by 2021. Asia Pacific is expected to have largest share in the automotive heat shields market among the other regions such as North America, Europe, Asia Pacific, Middle-East and Africa and Latin America. Growing population and the rising demand for luxury vehicles in countries such as China and India is driving the demand for automotive heat shields in the region. Other factors contributing to the growth of the Asia-Pacific market include high economic growth and urbanization boosting the GDP growth of countries. The European region is estimated to be the 2nd largest market for automotive heat shields, owing to the rising vehicle production volume and the growing trend of engine downsizing.
The automotive heat shield market is segmented on the basis of application type into engine compartment heat shield, under bonnet heat shield, under chassis heat shield, exhaust system heat shield and turbocharger heat shield, A vast majority of vehicles are equipped with exhaust system heat shields to reduce the amount of heat radiated by the exhaust system and to protect the other body parts of a vehicle. Therefore, the exhaust system segment is estimated to account for the largest market share. However, the turbocharger heat shield market is projected to grow at the highest CAGR, by value, of 10.1% from 2016 to 2021.
Nowadays, with the growing number of temperature-sensitive and sophisticated components in modern vehicles that have to be protected from heat, the management of heat is becoming complex. Heat shielding systems help engine and exhaust systems to function safely and reliably and contribute to enhanced driving comfort and environmental protection.
The demand of heat shielding technology has been increasing along with the number of applications in automotive industry. Hence the heat shield market is witnessing growing demand in the automotive industry. However, the sophisticated heat shield solutions increase the overall price of the vehicle thereby restraining the market growth as certain applications are restricted to high-end models.
Integrating acoustical performance into a heat shield is a growing trend in the market which allows the treatment of noise problems that were difficult to treat before due to the extreme temperature environments.
Nowadays, heat protection is also provided in the vehicle passenger compartments. The application is no longer limited to premium models and is further expected to see large scale adoption across all models by the vehicle manufacturers. Companies such as Lydall, Inc. provide interior as well as exterior thermal solutions. Interior products are designed primarily for front of dash regions or under-carpet where high temperature sources exist. Exterior solutions are designed to lessen excessive heat from the exhaust system, shielding the fuel systems or floor sheet metal. At present, the solutions available in the market are not just single wall but the multi-layer solutions are also available for higher temperatures.
The leading players in the automotive heat shield market include Lydall Inc., Delphi Automotive PLC, Federal-Mogul Corporation, Morgan Advanced Materials Plc, Dana Holding Corporation, ElringKlinger AG, Autoneum Holding AG, Inc., Covpress Limited and Thermo-Tec Automotive Products
