Laird (Dupont group) offers non-halogenated flame retardant EMI (electromagnetic interference) gaskets. With roots back to 1824, and after acquisitions including Emerson & Cuming, BMI, Steward, and Thermagon, Laird Performance Materials is today part of Dupont and specialises in materials for protection of electronic devices from harmful heat and disruptive electromagnetic interference. The company’s FOF (Fabric-over-Foam) gaskets, consisting of an electrically conductive fabric (e.g. nickel and copper loaded nylon) around a specifically formulated polyurethane core, provide electromagnetic shielding for applications requiring low compression force, high conductivity and superior shielding. The phosphorus PIN FR FOF gaskets achieve UL 94 V-0 fire performance and are available in various profiles and can be customised by die-cutting, punching etc.
