DYNAMAT XTREME is a Black, light-weight, elastomeric, butyl and aluminium vibrational damper for use on bulkheads, doors, floors, boot, roof and bonnets to reduce road noise and internal resonance.

When applied to a vibrating panel, noise is converted into silent energy.

It is supplied in thin (1.7mm), flexible, easy to cut and mould sheets which conform to curves and bond easily to sheet metal and other hard surfaces.

You can apply Dynamat in patches (25-50% area coverage) to dampen resonation of a specific panel, or you can apply it over an entire area (such as the floor, doors, or boot) to create a sound barrier and vibrational damper.

Even a small amount of Dynamat can make a big reduction in noise levels.

For example, applying Dynamat to the doors of your vehicle can reduce road noise by 3-6dB. 

Complete coverage of an average vehicle can reduce road noise by as much as 18dB!

We recommend applying Dynamat to any surface you can easily reach such as the doors, rear panels, bulkheads, floor, roof, boot or under the bonnet. 

Installing Dynamat requires only a few tools: Craft knife or scissors, roller tool, rags and a solvent-based cleaner.

Applying Dynamat to the panels around your car also prevents panel distortion by stiffening the flimsy sheet metal or fibreglass into a more solid non-resonant baffle. 

Suitable for use in temperatures between -10°C to +60°C (14°F to+140°F).

Material can withstand temperature extremes between -54°C to +149°C (-65°F to +300°F) and is highly resistant to ageing.

Acoustic Properties:

The acoustic loss factor "n" is used as a measure of a material's ability to damp structure-bourne sound by stating how much vibrational energy (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 (no vibration).

An undamped 1mm 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 (+68°F).

Multiple layers of Dynamat Xtreme improve sound damping even more.

Installation:

Use scissors, knife or die to cut Dynamat Xtreme to the desired size and shape before removing the release liner.

Next, 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.

Press the mat firmly into place, using a roller for larger pieces.

The roller reduces the risk of leaving air pockets, which reduce Dynamat's 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.
