O-ring seal / rectangular / foam / EMI shielding
conductive, conductive fabric over foam
The conductive gasket produced by Ghiringhelli are two kind: Conductive Foam Soft Seal and Conductive Foam Ultra Soft Seal in relation to the different comprimibility of their polyurethane foam core. They are made wrapping the soft or ultra soft foam core of Polyurethane or other elastomer with our electric conductive polyester woven: Faraday Nickel Copper Fabric, Faraday Silver Fabric and Faraday Copper Fabric.
Our conductive fabric over foam gaskets are low cost and permit to reach very easy at cost effective the EMC compatibility.
Conductive Foam Ultra Soft Seal is characterized by a low force of closure with great EMI RFI shielding performances reach about since 20% of compression.
The wide gap of closure (from 15% up to 80% of thickness) is a good solution also for grounding and equipotential electric of all electronic components or ESD problems.
The gaskets are good substitute of other more expensive shielding solution as beryllium copper finger strips.
The metallization is made with Nickel-Copper or Silver-Copper electro less or galvanic deposit on all single polyamide yearns and then weaved. This process permit to produce rip-stop polyester electric conductive fabric with high quality of electric and environment performances.
