New conductive plastic material targets harsh environments

Article Type: New products From: Pigment & Resin Technology, Volume 39, Issue 4

A new version of its premier conductive plastic shielding material, which offers enhanced fuel resistance and heat deflection under load (HDUL) specifications, has been announced by Chomerics Europe.

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, says the company.

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 allows greater design freedom and offers total cost of ownership savings of up to 65 per cent compared to metal-based shields. Space and weight savings of 50-75 per cent and significant 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, shielding effectiveness is up to 85 dB. The robust material can be moulded with sections as thin as 2.0 mm giving an exceptional strength to weight ratio. Complex features and geometries can easily be incorporated into designs.

Having the shielding functionality integrated into a moulded part means that significant cost and process savings can be made; the need for supplementary processes such as plating, painting and vacuum coating are all alleviated. Chomerics is able support the design of Premier conductive plastics as a complete solution incorporating additional gaskets and inserts where required.

Premier PEI based materials are RoHS compliant and have a UL 94 flammability rating of V-0. Excellent corrosion resistance enhances suitability for long field life applications and the material is recyclable in line with WEEE EoVL TCO legislation, says the company.
