[0002] Automotive cavity partition blocks are a type of sound insulation and heat insulation material used inside vehicles. They are mainly used to fill the cavities inside the vehicle body to improve the vehicle's acoustic performance and thermal management efficiency. These partition blocks are usually made of high-density plastic, rubber and foam materials and have good sound insulation and heat insulation properties. During the automobile manufacturing process, cavity partition blocks are placed in specific locations of the vehicle body, such as the engine compartment, wheel arches, door panels and roof to reduce noise transmission and heat transfer.
