Product Description

Dynamat Hoodliner

Contains one 32" x 54" piece of Hoodliner for under the hood of your vehicle. For best performance, use with Dynamat Xtreme.


The Hoodliner is a polyether, urethane-based, thermo-acoustic foam with a reinforced aluminized facing and a pressure-sensitive adhesive on the application side. The Hoodliner is designed to be die cut to shape and then applied in a vehicle's engine compartment to the underside of the hood. The adhesive side is smooth, ensuring complete contact with the underlying surface without any air pockets of channels. Both material and adhesive can withstand temperature ranges between -40°F and +225°F (-40°C to +107°C).


Acoustic Properties:

The effectiveness of an acoustic foam depends on its ability to convert sound waves into heat energy. Dynamic Control's Hoodliner has a combination of open and closed cells to accept and dissipate sound waves. If all the foam cells were open, sound waves would simply pass through. Conversely, if all the foam cells were closed, few sound waves would be absorbed. The acoustic foam in Hoodliner is cast in sheets for consistent resistivity levels throughout the foam, to assure maximum sound absorption.



Hoodliner is used to treat automotive engine compartments. It has a reinforced aluminized facing, which provides 97% heat reflection. This reflection reduces heat transfer to the hood and, thus, wear to the painted surfaces. It is also used in other applications requiring heat-resistive acoustic foams.



Use scissors, knife or die to cut Hoodliner to the desired size and shape before removing the backing paper. Next, remove dust, grease, moisture, and other foreign matter from the application surface. Peel off the backing paper. The simplest application technique is to bend the Hoodliner slightly and attach it along its shortest edge. Press the Hoodliner firmly into place. You may want to use a roller for quicker application.
