Car sound insulation cotton is generally located on the engine hood, behind and under the rear seats, on the doors, and on the floor, etc. The sound insulation cotton can improve the car's sound insulation performance and reduce noise entering the car. The sound insulation cotton on the car engine hood has many functions. This sound insulation cotton not only insulates noise, but also provides insulation in winter, allowing the engine to warm up quickly after starting in winter. It can also absorb some oil vapor generated during engine operation, protecting the paint on the engine hood.
