New Chomerics (by Parker Hannifin) Cho-Seal EMI Shield Gasket Material, .062" x .100" Conductive Elastomer, Part Number 10-05-4699-1285.  Each bid quantity is for One (1) Bag Containing Twenty-Five (25) Linear Feet.  You may bid / buy any number of bags, up to the total quantity available above.

This was purchased at an electronics supplier liquidation earlier this year, and it was brand new on the original factory spools.  We measured it and repackaged in heavy Ziplok bags for resale.  Chomerics 1285 is made with a silicone rubber elastomer that is impregnated with finely powdered Silver and Aluminum metal during the manufacturing process.  This gives it some interesting properties, such as conducting electricity and providing shielding against electromagnetic interference.  It is noticeably heavier than ordinary silicone rubber, but it is not as stretchy.  Hardness is around Shore 65 (+/-7).

Note:  About 95% of these bags should be one full, unbroken 25' piece of material.  We did, however, have a few bags with broken pieces that got mixed in with the others (about 15 out of 300 bags).  We will try to pull out any bags with "extra ends" as we ship them, but one could occasionally get through.
