New soft gaskets with gold finish deliver attenuation in excess of 100dB across a wide frequency range for applications requiring the highest performance.

New soft gaskets with gold finish deliver attenuation in excess of 100dB across a wide frequency range for applications requiring the highest performance.

The ECP 400 gold soft EMI shielding gaskets comprise a conductive fabric bonded over a soft nonwicking polyurethane closed cell foam.

The gaskets are ideal for shielding applications where high performance levels over a wide frequency range are required and particularly where low closure forces combine with a requirement for good environmental sealing.

All gaskets feature a self-adhesive strip to aid location and mounting.

A wide range of standard profiles is available cropped to any length up to 2m encompassing rectangular, flat, square, D-shaped, V-section, clip-on D-shaped, knife-edge, P-shaped, U-shaped, L- or J-shaped, keyhole and circular.

In addition to standard shapes, TBA ECP can provide custom designs with virtually no limitation to the design of the gasket profile and incorporating full or partial wrap of the conductive fabric.

Tailor made die cut shapes in widths up to 150mm can be produced.

Typical specifications for polyurethane foam include UL94V0 flammability rating and 6% maximum compression set.

The conductive fabric is woven polyester (nonwoven option available) with a gold conductive coating.

Surface resistivity is 0.05ohms/sq.

Offering excellent abrasion resistance, overall shielding effectiveness exceeds 100dB from 30MHz to 10GHz with temperature limit of 200C.

The new ECP 400 gold soft gaskets extend TBA's comprehensive line of EMI shielding products that encompasses nickel copper coated soft gaskets for standard applications, knitted wire mesh gaskets, woven wire sheet, metal foil tapes, oriented wire in silicone rubber, moulded and extruded conducting elastomers, printable EMI shielding elastomers, EMI shielding windows, honeycomb vents, shielded fan vents and quiet vents.

The company also offers an extensive line of beryllium copper and stainless-steel fingerstock for all EMI shielding applications.
