Summary
GORE-SHIELD GS2100 EMI Gasket is a conductive, adhesive
backed, EMI gasketing material that is moderately soft and is
approved for space ight and military applications.
GS2100 EMI Gaskets can be supplied in die-cut
GORE-SHIELD
part forms or in slit width rolls. Slit width material is ideal for
manual peel and stick EMI gasketing applications.
GS2100 EMI Gaskets consist of a carbon- lled
GORE-SHIELD
cellular PTFE matrix, a conductive pressure sensitive adhesive,
and a PET carrier lm (see Figure 1).
