Soft EMI shielding gaskets cropped to any length from TBA ECP

Keywords: Gaskets

EMI shielding specialist, TBA Electro Conductive Products (ECP) has announced that its ECP 400 series of soft EMI shielding gaskets can at present be supplied cropped to any length up to 2 m and in customised format. Short cut lengths can be supplied die-cut on backing sheets for ease of handling at the production assembly stage.

The ECP 400 series soft EMI shielding gaskets comprise a conductive fabric bonded over soft non-wicking thermoplastic polyurethane (TPU) 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 2 m 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. Tailor made die-cut shapes can be produced.

Various finishes are available including Nickel/ Copper (Ni/Cu) plated as standard and gold plated for higher attenuation.

Typical specifications for polyurethane foam include UL94V0 flammability rating and 6 percent maximum compression set. The conductive fabric is woven polyester (non-woven option available) and surface resistivity is 0.05 V/sq. Offering excellent abrasion resistance, overall shielding effectiveness is 68-88 dB from 30 MHz to 1 GHz with a temperature limit of 200°C.
