Which cars do not use asphalt damping sheets?
1 Answers
Cars that do not use asphalt damping sheets include Volvo. Below is relevant information about asphalt damping sheets: 1. Function: Asphalt damping sheets are made using asphalt as the raw material. They are applied to the inner surfaces of the vehicle body and serve as a viscoelastic material to reduce noise and vibration. 2. Types: They are mainly divided into hot-melt asphalt damping sheets, self-adhesive asphalt damping sheets, and magnetic asphalt damping sheets. The primary types used in vehicles are hot-melt and magnetic asphalt damping sheets. 3. Product differences: The production processes for the three types of asphalt damping sheets are similar. The difference lies in the fact that self-adhesive and magnetic types require more processing steps than the hot-melt type. 4. Environmental performance: Polyolefin polymer materials have passed the EU ROHS test and are harmless to humans. In accelerated thermal aging tests, the performance of asphalt damping sheets sharply declines after 150 hours, and they release harmful substances more quickly when heated.
