The automotive damping sheet industry has broad development prospects and needs to continue to upgrade in the direction of green and environmental protection in the future.

Automobile damping sheets, also known as clay or damping blocks, refer to a type of viscoelastic material attached to the inner surface of the car body (including doors, side panels, trunk floor, body chassis, etc.), which mainly plays the role of noise reduction and shock absorption. According to different materials, automobile damping sheets can be divided into asphalt-based damping sheets, rubber-based damping sheets and other polymer-based damping sheets.

Car damping sheets are one of the important parts of the car. An ordinary car uses about 10 damping sheets. Currently, driven by the steady growth of domestic automobile production and sales, the market demand for automobile damping sheets continues to increase. According to data from the China Association of Automobile Manufacturers, my country’s automobile production and sales in 2022 will complete 27.021 million units and 26.864 million units respectively, a year-on-year increase of 3.4% and 2.1% respectively. As one of the indispensable parts of automobiles, the market size of damping sheets continues to increase, and the industry shows good development prospects.

According to the “2023-2028 Automotive Damping Sheet Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center It shows that from the perspective of market segments, asphalt damping sheets are the mainstream product in the domestic automotive damping sheet market, and currently cover more than 90% of vehicle types. According to different production processes, asphalt damping sheets can be divided into three categories: magnetic asphalt damping sheets, self-adhesive asphalt damping sheets and hot-melt asphalt damping sheets; according to different raw materials, asphalt damping sheets can be divided into coal tar asphalt damping sheets, petroleum asphalt damping sheets Damping sheets, natural asphalt damping sheets, etc.

Asphalt damping sheets have the advantages of low cost, good temperature resistance, long service life, good damping effect, and easy maintenance. However, they also contain carcinogens such as benzene and benzopyridine, which will release a variety of toxic gases when heated. , posing a great threat to human life safety, among which coal tar asphalt damping sheets are the most harmful. At present, alternatives to asphalt damping sheets mainly include butyl rubber damping sheets, PVC plastic damping sheets and other polymer resin damping sheets.

Compared with asphalt damping sheets, butyl rubber damping sheets have the characteristics of non-toxic, harmless, green and environmentally friendly, stable damping performance, and longer life. They are one of the segmented products with great development potential in the future automotive damping sheet market. However, due to cost factors, the market penetration rate of butyl rubber damping sheets is still relatively low. In the next 3-5 years, asphalt damping sheets will still be the mainstream product in the domestic mid-to-low-end automotive damping sheet market. In the future, domestic enterprises will need to continue to make breakthroughs in key technologies to accelerate the cost reduction and efficiency improvement process of green non-toxic damping sheets, which will in turn accelerate their replacement of asphalt damping sheets.

Industry analysts said that green non-toxic damping sheets are expected to replace asphalt damping sheets and become the mainstream product in the automotive damping sheet market. In the future, as national living standards continue to improve and awareness of health and environmental protection continues to strengthen, national expectations for the stability and efficiency of automobile performance and the safety and environmental protection of materials will continue to increase. Efficiency, safety, and environmental protection will become the mainstream development trend of the automobile and automobile materials industry. . As one of the key components of automobiles, automobile damping sheets need to be continuously upgraded in the future to be green and environmentally friendly, and to accelerate the comprehensive replacement of traditional asphalt damping sheets with green non-toxic damping sheets.
