While Dupont mentions a larger mass molded Teflon device, perhaps for larger scale non-audiophile applications, the Dupont Teflon PTFE Properties Handbook includes Teflon as an effective vibration control material with excellent vibration dampening properties both at sonic and ultrasonic frequencies (see PDF file download link below):

Miscellaneous
Molded TeflonŽ PTFE fluoropolymer resins have excellent vibration dampening properties both at sonic and ultrasonic frequencies. Installations for this purpose have been very successful. The thickness of material required must be sufficient to absorb the energy produced and is usually determined experimentally.

Duster,
Had previously installed a Marigo Audio White VTS Tuning Dot on each removable RAM chip of the computer that plays ripped tracks from an external drive and they caused a nice increase in musical detail.
Today I inserted a narrow single strip of Teflon tape between the side edge and the retaining clip of each chip and heard a 300% greater improvement. For those of us playing music out of our computers this is a most rewarding application.

Just saw this post. Do you really mean to say that the sound was 3-fold better because of a piece of teflon tape? When I see statements like that, I have to think that the sound was fairly poor or mediocre to start with, with noticeable deficits in frequency response and obvious distortion. Was that the case?
Lew,
The threefold improvement was in relation to the initial audible, but small, improvement contributed by a Marigo Audio White VTS Tuning Dot on each RAM chip.

many plastics have excellent damping properties. 3M manufectures.many as does Du Pont.
The 3M tube dampeners i mentioned was left over from some aerospace project which got canned. As such, it was unfortunately a limited availibility product. In examining other 3M products, the closest i can find (limited resources) is the substrate used in their VHB tapes, clear substrate, red backing tape. Very sticky, though, and definitely heat sensitive, as was.original tube dampers. It worked fine on small signal tubes, though i would avoid using them on power tubes (they melt).
I believe they are a polyurethane construction, FWIW. They have a phenonenal ability to stretch and then recover, probably an explanation for their damping abilities.
FWIW and YMMV
