15 years later I worked with two of the foremost Auxetics experts, husband and wife, Kim and Andy Alderson.

You sure have a talent for finding "moon rocks"
;-)
Does look like interesting material.

Circuit Boards - Dave's toner-transfer freezing
technique
Rick
A while ago I had some samples of Auxetic foam gasket
material that I used on a pumping system. It is peculiar
stuff in that if you stretch it it grows in diameter and if
you squash it, when using it as a gasket, it expands to fill
all the voids. Clamped between the band and the transfer
sheet it would ensure even pressure distribution.
See:

for an explanation.
I can't remember who made it but it was reasonably
priced.
An alternative would be to use a rubber gasket material.
