When used as an interface in audio electronic applications, this heat-resistant, vibration-control material minimizes microphonic influence. Custom-formulated, silicone-based viscoelastic is firm, just barely "squishy," and compliant. Use as an interface between component shelf and rack, between platform and shelf, under mass-loading weight, wherever a compliant interface is needed for superior vibration control or decoupling. Provides superb isolation with turntable and plinth applications. Effective throughout a broad range of weight loads. 1/16" (1.6mm) thick.

Optional pressure-sensitive adhesive on one side bonds well to most materials. (Adhesive can be applied to both sides by special request.)

Thin grungebuster Dots: Same as above, except 1/32" thick (.8mm). Use between constrained layer materials instead of adhesive for superior damping and wherever a slightly compliant decoupling interface is desired. Ideal as an interface between cones and component or shelf - placing a grungebuster Dot on the flat side of a cone absorbs vibration and allows the cone to work more efficiently with a little less of its own "character." Though rarely needed, all Thin grungebuster Dots are available with optional pressure-sensitive adhesive on one side (or on both sides by special request). Black grungebuster Dots are a little firmer than off-white grungebuster Dots, better suited for loudspeaker applications and other uses where a firmer interface is needed.

Damping Sheets: Cut your own Dots, squares, gaskets, anything. Cuts easily with razor blade, hobby knife, or scissors. Heat resistant, highly flexible microphonics-absorbing/decoupling/isolation materials. Great as a decoupling interface between different materials and as a damping layer in constrained layer systems.

grungebuster: Versatile, multi-purpose damping/isolation.

dBNeutralizer: Ideal for component chassis damping and loudspeaker applications. At 140 grams per 5" x 8" sheet, this damping sheet is nearly three times heavier and vastly more effective than equivalent-size 3M Damping Sheet.

Adhesive: Damping sheets are available with optional pressure-sensitive adhesive (except GIANT dBNeutralizer). Silicone medical adhesive can also be used as a superior adhesive. Here are links to three very good adhesives:

Hollister #7730 Medical Adhesive (small spray can)
Secure II Medical Adhesive (small bottle w/brush-on applicator)
3M Pressure-Sensitive Adhesive (double-sided adhesive tape)

All damping sheets are 5" x 8" (except dBNeutralizer GIANT 9" x 12" sheet)

What it is: Herbie's isolation materials are silicone-based vinyl elastomers with variable compliance, firmness and specialized qualities. The materials will absorb vibration with very little pressure applied, yet will handle a lot of weight. These compliant, non-vulcanized compounds are not dependent on a precise weight load to be most effective. They are equally effective under a wide range of weight and have little or no resonant "coloration." These materials are unsurpassed in their ability to absorb microphonic vibrations and reduce audio distortion. Materials are smudge-free and residue-free, with excellent dielectric (insulating) properties.
