Source car special sound-absorbing material for automotive sound insulation cotton sound-absorbing cotton

Product description automotive sound insulation materials is rubber foam, fire-retardant insulation effect with insulation: Car engine noise can sound engineering, vibration, body resonance door, when driving with the road surface, air resistance generated by friction sound, etc., effective elimination and sound, giving you a quiet driving space, greatly improved driving comfort. Insulation: Sound engineering not only sound, but also effectively generate high-temperature operation of the engine outer barrier, improve the air conditioning effect, make you feel cool. Strengthen the body: cover the body, doors, back-up cabin, roof, fender noncritical Sheet metal parts are relatively weak, after the installation of insulation material, the body is more robust collision, the passive safety factor is improved. Optimization of sound: sound, especially rear-mounted subwoofer, will lead the trunk vibration, sound decreases, which is not done properly because of damping, structure of an automobile can not afford bass impact, issued a "creak "Sound. After construction noise, eliminating the resonance body of metal, and also a good sound-absorbing effect, you can feel the sound more clear, vigorous, surging.
