7 mm Black Rubber Foam Heat Insulation Mat Soundproofing For Car
|Material||Rubber foam + Fiber glass|
|Other Thickness||20mm / 25mm|
|Fire Proof Class||B1|
|Density||55 kgs / m³|
|Noise Reduction||High Reach to 30 DB(A)|
Made of the EPDM Strong spongy material. It composite a high
reflective aluminum foil on the surface and it can reduce the heat
from the engine and protect the painted surface of the hood. There
is independent obturator spongy material in the middle,its heat
conductivity is 0.034W/ mk with great character of heat-proof and
It is very easy that you could do it by yourself !!
Clipping due to the size of your car’s engine cover, it is very
simple! The size of the sound insulation cotton is big enough for
the application of the car engine.
Note: Inflaming won’t be not burning, it means that the kindling
point is relatively higher and if touched by a tongue of flame it
wound put off by itself(even the iron would melt, so not won’t be
Methods to deal with sound-proof
Usually we have two methods to deal with this problem.
Firstly we could apply the sound-proof and shock- proof products.
For example, if we stick some sound-proof and shock-proof materials
to the doors and the luggage site, it will help to reinforce the
car structure and control the resonance between the body and the
outside environment. This is because these materials will change
the former rates and control the resonance and consonance and cut
off the noise made by the car.
Secondly we could use these materials to reduce the noise. For
example, when we apply the sound insulation materials into the
engine, the noise will be greatly reduced. This is because that the
sound insulation material is an Acoustic foam material which
contains the open mouth chamber and the inside-closed chamber. This
will transform the noise in to mechanic power and heat and
eliminate the noise. These two materials will not be separated, we
have combined them together and reach the best effect.
The Benefits of the automobile sound-proof materials:
1. It will revert the sound pressure and the tone quality of the
automobile stereos by using the shock-proof materials to damp and
seal the sheet metals and develop the installing environment of the
2. It will debase the noise made by the sheet metal structure of
the car and support you a comfortable condition by using the
shock-proof and the sound-proof materials.
Sound Insulation of the automobile:
The four doors double, back trunk, chassis, four-wheels and wings
board, engine cover
The four doors double:
it forms a case body in the door board and helps the working
efficiency of the horn and reduces the shock of the car door and
the wind’s noise.
it reduces the noise of the road and the steel; reduce the shocking
of the air.
