Insulating Dynamat Hoodliner

Description

DESCRIPTION
The Hoodliner is a Polyether Urethane Based with a Reinforced
Aluminized Facing and Pressure Sensitive Adhesive on application
side, thermo-acoustic foam. This product is made to be applied
inside the automotive engine compartment to the underside of
the hood. Product shall be die cut to shape and placed onto the
under hood surface. Adhesive side is smooth, giving complete
contact with the underlying surface without any air pockets of
channels. Both material and adhesive can withstand temperature
ranges between -40C to +107C (-40F to +225F).
ACOUSTIC PROPERTIES
The effectiveness of an acoustical foam is dependent on its ability
to convert sound waves into heat energy. Hoodliner has a combi-
nation of open and closed cells to accept sound waves and dissi-
pate them. If all of the foam cells were open, sound waves would
simply pass through. Conversely, if all of the foam cells were closed,
few sound waves would be absorbed. The acoustic foam in Hood-
liner is cast in sheets, achieving consistent resistivity levels through-
out the foam. Thus, maximum sound absorption is assured.
HEAT RESISTIVE PROPERTIES
Hoodliner has a reinforced aluminized facing which provides 97%
heat reflection. This reflection reduces heat transfer to the hood
and reduces wear to the painted surfaces.
APPLICATIONS
Hoodliner is used as an automotive engine compartment treat-
ment. It is also used in other applications requiring heat resistive
acoustical foams.
INSTALLATION
Hoodliner should be cut to the desired size and shape before the
release liner is removed. It may be cut with scissors, knife, or die.
Remove dust, grease, moisture, and other foreign matter from the
application surface. Peel off the release liner. The simplest appli-
cation technique is to bend the Hoodliner slightly and attach it
along its shortest edge
