Search engine hood sound SMPS MPPS v5 insulation technology!

Engine hood peritoneal is a kind of polyether SMPS MPPS v5 type of polyurethane insulating acoustic foam, the outside is coated with enhanced aluminum coating, interior surface is coated with a layer of pressure sensitive adhesive. This product is most suitable for use in car engine cabin, the general must stick engine hood of the side. Products in the stick to engine hood under the surface of the prior to punching forming. Compared with viscose side of smooth, this film can and engine hood lower surface for close contact, without in the middle form bubble. Film and adhesive material can be resistance temperature field is - 40 ℃ to + 107 ℃.

Acoustic features:

The effectiveness of SMPS MPPS v5  acoustic foam mainly depends on it will sound waves into the ability of heat energy. Engine hood coated on the open and not open sound-absorbing cavity, they can absorb and consumption acoustic energy. If all sound-absorbing cavity are open, the voice will from it through. Conversely, if all sound-absorbing cavity are closed, the material can absorb a few sound waves. Engine hood coated on the sound absorbing cavity is made of die shape, so the whole piece of material sound-absorbing level is uniform. This helps to ensure that the material can obtain the best sound absorption effect.

Insulating properties:

Engine hood on coated with a layer of enhance the aluminum film, it can reflex 97% of heat. It can reduce the quantity lexia of heat to the engine hood, prolong the service life of spray paint surface.

Application:

Engine hood coated the most suitable for automobile engine in use, can also be used to other need insulation acoustic foam material occasions.
