Dynamat is a patented, lightweight elastomeric butyl and aluminium constrained-layer vibration damper. Dynamat conforms and fuses easily to sheet metal and other hard substrates. Material performance is optimised for temperature ranges between 14°F and 140°F (- 10°C to +60°C). Material can withstand temperature extremes between -65°F and +300°F (-54°C to +149°C) and is highly resistant to aging.

Discover the Dynamat Difference:

You want to consider several things when you compare Dynamat to other materials. Dynamat exceeds other materials because of proprietary VECTOR™ Chemistry and damps better at an extended higher temperature range. Dynamat does not absorb moisture and is not affected by oil. Its elastometric “space age” synthetic rubber will stay intact under foot and sticks to overhead, vertical and oily surfaces. It is much easier to do a better job with Dynamat’s larger sheets of 3, 4 and 8 square feet while imitators can have less than 2 square feet. Dynamat is and has been made in the USA for over 20 years. We guarantee it!


Dynamat can be die cut to shape and placed onto the body surface directly on painted panels or after the sheet metal is cleaned before painting (typically at the sealer application operation). Dynamat is used to treat metal panels, partitions, ducts, doors, bins, panels, and so forth in automobiles, railroad cars, buses, and ships. It is also used for ventilation ducts, relay cabinets, steel furniture, home appliances, sink units, computer equipment, machine tools and many other objects that suffer from vibration-produced noise.
