Conductive foam material, characteristics and uses

Conductive foam is widely used in PDP TVs, LCD monitors, LCD TVs, cell phones, notebook computers, MP3s, communications cabinets, medical instruments and other electronic products as well as military and aerospace fields. And with a very high price/performance ratio, it is the latest and most widely used shielding material.

The conductive foam is wound with a conductive braiding sleeve on a foam core made of polyurethane or EPDM. The conductive braided sleeve is usually made of silver-plated nickel nylon, aluminum foil or Monel wire (nickel-copper alloy) Ferrex (tin-plated). Copper-clad steel wire) has good electrical conductivity. Meets flammability rating (UL94-V0), with good mechanical properties such as elasticity and flexibility. The conductive foam pad has good shielding performance. When it encounters electric waves, it will reflect, absorb and provide excellent shielding effect according to the nature of the object. After the conductive cloth is wrapped on the fire-retardant sponge, after a series of treatments, the conductive foam has a good surface conductivity, and it can be easily fixed on the device to be shielded with an adhesive tape. Foams are available in different profile shapes, installation methods, UL ratings, and screen shielding materials.

Conductive foam can be divided according to the material: aluminum foil cloth foam, conductive fiber cloth foam, gold plated cloth foam, carbon fiber cloth foam and other conductive foam characteristics and advantages of RoHS compliant Z axis resistivity can be great Shielding efficiency increased to over 90dB in frequency range Suitable thickness 0.039" ( 1mm), 0.060" (1.5mm), 0.079" (2 mm), 0.098" (2.5 mm), 0.125" (3.2mm), width up to 0.250 "(6.4mm) Large compression range, up to 60% of original thickness. Also available with UL94 HB and V0 flammability ratings for many standard configurations including D-subs, USB port, IEEE 1394, SCSI and RJ 11. (Also suitable for thin plates and rectangular shapes) Can be punched into the desired shape Punching I/O, Rectangular liners and panel liners Available with back conductive adhesive or no back conductive adhesive Low residual distortion guarantees product Long-term use performance.
