Design Ideologies
Make your vehicle a better one. When it comes to making your hot rod ride like a luxury car, Dynamat does the job. Dynamat is used by the world’s top hot rod and custom builders because they know it makes their cars ride cool and quiet. Dynamat makes cars feel solid; doors and trunks slam snug, rain and wind virtually disappear and your interior becomes a quiet comfortable cruising environment. Use Dynamat Xtreme on the interior sheet metal of your vehicle to stop vibration and reduce road noise. Add a Dynamat brand thermoacoustic liner such as Dynaliner to fight heat and low frequency hums from big engines and exhaust systems. This will net you the ultimate ride. Put simply; Dynamat is the ultimate automotive accessory.
Stop vibrating sheet metal and road noise! High vehicle noise levels cause driver fatigue and irritation, and will affect the way music sounds out of speakers. When the vehicle is noisy music and conversations can sound unclear and distorted. Dynamat Xtreme is the highest efficiency sound damping material available and the most effective product for stopping noise and vibration in your automobile.
Design Features
Dynamat Xtreme is a patented light-weight, elastomeric, butyl and aluminum constrained-layer vibrational damper. Dynamat Xtreme conforms and fuses easily to sheet metal and other hard substrates. Material performance is optimized for temperature ranges between -10 °C to +60 °C. However it can withstand temperature extremes between -54 °C to +149 °C and is highly resistant to aging.
Acoustic Properties
The acoustic loss factor n is used as a measure of ability to damp structure-borne sound. It states how much vibrational energy, say in steel sheets for instance; is converted to heat rather than sound. For constructions containing several layers of damping material, the combined loss factor n comb is used. The theoretical maximum loss factor is 1, or no vibration. An undamped 1 mm thick steel panel has a loss factor of roughly 0.001 at 200 Hz. Dynamat Xtreme applied to that panel would increase the loss factor to 0.417 @ +20 °C. Multiple layers of Dynamat Xtreme can be used to improve sound damping further.
Application
Dynamat Xtreme can be die cut to shape and placed onto the body surface after sheet metal cleaning operation and prior to paint system; typically at the sealer application. Dynamat Xtreme is used as treatment for metal panels, partitions, ducts, doors, bins, panels etc. in railroad cars, buses, automobiles and ships. It is also used for ventilation ducts, relay cabinets, steel furniture, home appliances, sink units, computer equipment, machine tools and for many other purposes.
Installation
Dynamat Xtreme should be cut to the desired size 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 application technique is to bend the mat slightly and attach it along its shortest edge. The mat is then pressed firmly into place, preferably with a roller for larger pieces. This reduces the risk of leaving air pockets, which reduce the sound damping capacity. The temperature of the mat and application surface should not be below room temperature during fitting. Heating the material is not necessary.
