What Is Soundproof Cotton?

Sound insulation cotton has good heat insulation effect. After being affixed in the hood of the car, it can effectively prevent the high temperature of the engine from being directly transmitted to the hood, thereby protecting the paint on the surface of the hood and avoiding the fogging effect of the hood on rainy days.

Another function of the sound-insulating cotton is to insulate it, so that it can reduce the heat that the engine runs to the surface of the hood. Vehicles with hood insulation cotton will not produce white fog on rainy days. On rainy days and winters, due to the large temperature difference between the outside air temperature and the engine, coupled with the scouring of the hood by rain, etc., the oxidation of the paint surface is accelerated. Insulation cotton can protect the lacquer finish of the hood to a certain extent
