Chomerics Europe has introduced a new version of its “Premier” conductive plastic shielding material that offers enhanced fuel resistance and heat deflection under load (HDUL) specifications. Complementing the existing range of Polycarbonate/ABS based materials, the new derivative uses a Polyether Imide (PEI) resin and is ideal for use in the most demanding applications such as those found in military and aerospace designs.

The 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, It allows greater design freedom and offers total cost of ownership savings of up to 65% compared to metal-based shields. Space and weight savings of 50 to 75% and space savings can also be achieved when using the materials.

The high HDUL of PEI based Premier conductive plastic allows stable performance at temperatures up to 180°C (360°F), shielding effectiveness is up to 85dB. The robust material can be moulded with sections as thin as 2.0mm giving an exceptional strength to weight ratio. Complex features and geometries can be incorporated into designs.

The materials are RoHS compliant and have a UL 94 flammability rating of V-0. Corrosion resistance enhances suitability for long field life applications and the material is recyclable in line with WEEE EoVL TCO legislation.
