Conductive plastic shielding material

Chomerics Europe, a division of Parker Hannifin, has introduced a new version of its PREMIER conductive plastic shielding material, designed to offer enhanced fuel resistance and heat deflection under load (HDUL) specifications.

The new derivative uses a Polyether Imide (PEI) resin and is suitable for use in applications such as those found in military and aerospace designs. PREMIER conductive plastic shielding materials consist of nickel-plated carbon fibres integrated into an injection moulded thermoplastic resin resulting in finished parts with high mechanical strength. Developed for high performance EMI shielding and grounding applications, PREMIER is designed to allow greater design freedom and offer total cost of ownership savings of up to 65% compared to metal-based shields. According to Chomerics, space and weight savings of 50 to 75% and significant space savings can also be achieved when using the materials. The conductive plastic is said to allow stable performance at temperatures up to 180°C , shielding effectiveness is up to 85dB. The material can be moulded with sections as thin as 2mm and Chomerics says that complex features and geometries can easily be incorporated into designs.
