Conductive metalized fabrics Gaskets GT 60000

Conductive metalized fabrics are structures made from polyamide synthetic fibers coated with metallic
conductive materials (copper, nickel, silver). These metalized fabrics fixed on silicone or various foam supports l Foam Foam
make it possible to create shielding gaskets for computer applications, mobile radios, cell phones and other l
electronic instruments.

Use
The thickness of the foam coupled with the softness of the fabric considerably 0.5-6.3 +/- 0.5 5.0-150.0 +/- 0.8
improve contact between the fabric and the printed circuit shielding screens. 6.3-10.0 +/- 0.7 151.0-300.0 +/- 1.3
The foam is slightly compressed between the top and the upperedge of the
screens, thus increasing the pressure of the fabric on the various parts in 10.0-16.0 +/- 0.8 301.0-1200.0 +/- 2.5
