Can the car soundproofing cotton still be used if it gets wet?
1 Answers
Car soundproofing cotton cannot be used if it gets wet and needs to be replaced with new soundproofing cotton. The function of car soundproofing cotton: Soundproofing cotton has excellent thermal insulation properties. After being installed under the car hood, it effectively prevents the engine's high temperature from directly transferring to the hood, thereby protecting the hood's surface paint and avoiding the formation of fog on the hood during rainy days, which could affect visibility. How car soundproofing cotton works: Vibrating objects produce sound — sound waves travel through the air — the cotton has a multi-fiber structure — when sound waves pass through the cotton, they undergo reflection, overlapping, and collision among countless fibers, converting sound wave energy into heat energy — the sound wave intensity weakens — the sound disappears.
