GORE-SHIELD® GS8000 EMI Gaskets
GORE-SHIELD® GS8000 is a versatile, conductive gasket material that provides excellent EMI shielding effectiveness for portable wireless devices. GS8000 is the ideal gasket solution for wireless applications that employ non-metallic housing materials and thin circuit boards.
GORE-SHIELD® GS8000 is a soft, highly compressible material. It provides high shielding effectiveness with low closure forces. These lower closing forces reduce stress on device housings and circuit boards. Specialized dispensing machines are now available that can used to place even small, intricate gasket shapes of GS8000 automatically, at high production rates.
