Integral Introduces Conductive Plastic Materials for High Performance Shielding Market

Published on 2014-11-12. Author : SpecialChem

Integral Technologies, Inc., among the emerging light weighting leaders and its wholly owned subsidiary, ElectriPlast Corp, announced the exciting development of two new materials. These materials keep Integral well in front of the industry performance curve. The focus of these new materials is the high performance shielding market and applications that will utilize ElectriPlast as a conductor. These new products will be protected by existing patents, with additional opportunities to add to Integral's IP portfolio from innovations achieved during product development.

The first material is a lightweight, high strength conductive material with an inner core of un-plated 12K and 24K carbon fiber, the second material is a highly conductive material using copper plated carbon fiber ("CuC"). Both materials can be formulated with most base resins, including ABS, PA66, PBT, PC, and PP.

"These new products are a continuation of our product portfolio expansion to meet our customers' growing needs," stated Mo Zeidan, ElectriPlast's Chief Technology Officer. "Selecting the right ElectriPlast pellet is critical in creating a solution for a successful application and these two new products provide additional options." The unplated carbon fiber pellet is a lower cost solution for applications requiring lightweight, EMI shielding, specifically consumer electronics products where shielding is critical, but also require strong, lightweight materials for mobility purposes. Depending on the loading of the carbon fiber to resin, attenuation ranged from 30dB at 30Mhz to nearly 55dB at 3 Ghz with wall thickness between 1mm to 3mm. Higher loading of carbon fiber will increase the shielding effectiveness. "For those applications where cost is a major driver, including consumer electronics, this product is the perfect mix of performance and price," stated Zeidan.

Increased requirements for light weighting and resistance to harsh environments have created an opportunity for highly conductive polymers to replace metal conductors in future applications. "Polymers capable of carrying high current with low ROA did not exist and our focus has been on creating material formulations, product processes and product interfaces to enable functional electric heaters, highly conductive traces and grounding planes," stated Slobodan ("Bob") Pavlovic, Vice President Engineering for ElectriPlast. "Different formulations were tested with continuous current ranging from 1A to 100A resulting in product temperatures well below heat deflection temperatures of selected polymers. We see great opportunities for this product line in the area of integrated heaters, ground planes, 3D PCB's, and integrated antennas. In parallel with material development, our applications engineering team is developing design solutions, making and testing prototypes to prove the technology and create product design to meet customer specifications."
