Whether aluminum foil insulation cotton have a role?
First talk about the noise cotton: cotton insulation from the outside look at a strip of aluminum foil and one without. That a major role is the use of aluminum foil with aluminum foil to isolate engine heat reflection barrier heat to affect the hood hood paint.
Cotton insulation aluminum foil using superior nitrile rubber, PVC as the main material, the complex process of foaming. Aluminum foil insulation cotton by aging tests, the useful life of more than 30 years, and after compliance with the aluminum foil layer can further improve the noise factor of the material.
Product Features:
1, aluminum foil insulation cotton sound absorption, shock absorption, excellent sound-absorbing effect by detecting the absorption coefficient as high as 0.85, the acoustic noise damping materials, high-performance products.
2, aluminum foil insulation cotton thermal conductivity, excellent heat insulating effect.
3, cotton insulation aluminum foil, low water absorption, closed bubble structure and dense skin easily through the water gas.
4, aluminum foil insulation cotton flame retardant, fire-retardant material contains large amounts of smoke reduction materials, smoke density generated during combustion is very low, and fire does not melt, does not drip on fire fireball, a material having self-extinguishing characteristics.
In summary aluminum foil insulation cotton very useful.
Of course, the biggest role is soundproof insulation cotton friends, followed by insulation, which can reduce the spread of heat engine operating surface of the hood, the installation does not produce mist have basic insulation cotton hood of the vehicle when the rain. Rainy days and winter, due to the larger temperature difference between the outside temperature and the engine, together with the joint action of the hood rainwater scouring right, will accelerate the oxidation of paint. Cotton hood insulation to protect the paint to a certain extent.
