Dynamat Xtreme Bulk Pack (one pack = nine 45x81cm sheets) (Bulk Buy x 3 packs)
Quality Dynamat product. Great value Dynamat Bulk Pack. Contains nine 45 cm x 81 cm sheets of Dynamat Xtreme, giving 3.3m² coverage.
Dynamat is a thin, flexible, easy to cut and mould sheet, that stops noise causing resonance and vibration by using visco-elasticity that promotes vibro-acoustic energy conversion. In short, this is a great quality sound proofing agent!
You can apply Dynamat in patches (25-50% area coverage) to keep a specific panel from resonating or you can apply it over an entire area (such as the floor, doors, or trunk) to create a sound barrier and vibrational damper.
Even a small amount of Dynamat can cause a profound noise reduction. For example, applying Dynamat to the doors of your vehicle can reduce road noise from 3-6dB. Complete coverage of an average vehicle can reduce road noise 9, 12 even as much as 18dB! We recommend applying Dynamat to any surface you can easily reach such as the doors, inner rear panels, bulkheads, floors, inner roof, nose panel or under the bonnet.
Installing Dynamat requires: razor knife or scissors, roller, rags and a solvent- based cleaner (rubbing alcohol also works).
Dynamat Xtreme is a patented, lightweight elastomeric butyl and aluminium constrained-layer vibrational damper. Dynamat Xtreme 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). The material can withstand temperature extremes between -65°F and +300°F (-54°C to +149°C) and is highly resistant to aging.
Acoustic Properties: The acoustic loss factor "n" is used as a measure of a material's ability to damp structure-borne 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.
Applications: Dynamat Xtreme 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).
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.
Appearance: Black butyl based core with 4 mil aluminium constrain layer, craft paper release line.
