Material Selection Prevent galvanic corrosion Materials / galvanic corrosion To avoid galvanic corrosion it is important that the potential difference between the joined materials is not too high. The difference in voltage between any two materials is an indication of their compatibility and the following criteria are commonly used: • Harsh environment (exposure to salt spray/weathering) no more than 0.3 volts • Benign environment (indoors, salt-free condensation only) no more than 0.5 volts Material enclosure Zinc die-casting alloy passivated Zinc plating on steel, chromate Cadmium plating on...

Amucor Shield 68OO Screwed applications for zinc plated steel and aluminum For panels and screwed applications. With and without self adhesive strip Amucor Shield 6800 is an economical HF gasket which can be supplied in a wide range of dimensions. It is very effective in combination with zinc-plated steel and aluminium constructions. All gaskets can be provided with a (conductive) self-adhesive strip. Amucor Shield 6800 consists of a neoprene or PVC foam core covered with reinforced foil, based on an Amucor alloy. This guarantees excellent shielding performance and very great strength. For special...

Ultra Soft Shield 74OO For doors and panels, where very low closure force is required Very low closure force to prevent bending of doors, lids and panels Ultra Soft Shield 7400 is an HF shielding gasket with high shielding performance and extremely low closure force. This prevents deflection of doors/parts, which improves shielding effectiveness. The core consists of a high-grade polyurethane foam core 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...

Other dimensions on request. xFoam core • Cut into specific lengths • Combination with water seal • UL94V-0 flame retardant foam core • Chemical resistant rubbers like EPDM • Silicone sponge for high temperatures up to 220°C • Different conductive foils and fabrics Ultra Soft Shield 7400, 9 x 6 mm, standard self-adhesive, standard polyurethane...

Metal Knit Gaskets 12OO For military applications, to shield lower frequencies The 1200 series EMC gaskets consist of a core covered with knitted mesh. In most cases the gaskets are made of sponge, hollow tubes or extruded elastomers. For special applications like EMP or high temperatures a fully metal version is available. Temperature resistance depends on the core material, but ranges from -60o C to 180oC. These gaskets are insensitive to external influences and can withstand harsh conditions very well. Also available with separate neoprene or silicone water seal. The maximum deflection with...
