Ultra Soft Shield 7400

For doors and panels, very low closure force to prevent bending of doors, lids and panels. Very soft gasket.

Ultra soft shield 7400 series is an HF-shielding gasket with high shielding performance and extremely low closure force. This prevents deflection of doors/parts, and improves shielding effectiveness. The product works very well in combination with stainless steel and other metals.

The core consists of high-grade polyurethane foam with a maximum compression of 80%, which distinguishes Ultra soft shield 7400 from other commonly used shielding materials.

Ultra soft shield 7400 is covered with a highly conductive, wear and tear resistant, metallized fabric.

Different foam cores and conductive foils/fabrics are available for special applications.

Tape specification:

01 Standard self-adhesive placed in the middle
02 Without self-adhesive
03 With conductive self-adhesive
06 Standard self-adhesive, asymmetrical

Foam specification:

P Standard polyurethane foam
F Flame retardant UL94V-0 foam

Benefits:

Gasket can be compressed up to 80%
Very low closure force
Very high electrical conductivity
High shielding performance
Roll lengths of 1 to 1000 meters, depending on width and height of the EMI gasket
Easy to fit with self-adhesive
High abrasion resistance
Can be cut with a pair of scissors
Because the Ultra soft shield 7400 series is so soft, it is easy to bend around corners

Options (on request)

Cut into accurate lengths
Ultra soft shield 7400 series combined with a water seal (see our Ultra soft twin shield 7800 series)
With UL94V-0 flame-retardant foam core
With chemical-resistant rubbers like EPDM
With silicone-sponge core for high temperatures up to 220 °C
Different conductive foils and fabrics
Bites or shapes cut out for easy application or bends, possible according to customer drawing

Our Ultra soft shield 7400 series is very easy to compress

Ultra soft shield 7400 series can now also be supplied in sizes as small as 3 x 3 mm

Ultra soft shield is commonly used for shielded doors to prevent bending of the door

Shielding profile shapes

These special profile shapes are made of EPDM rubber and due to the convex and/or concave shape, they can be compressed with little force.

High deflection version

We carry a combination of gaskets for an extremely high spring range. These gaskets are for applications where a high deflection and a high spring range is required. For an example a 26 mm high deflection gasket can be compressed up to 7 mm without overly exerting excessive force. That is 70% compression at low force.
