EMI shielding nearly doubled with carbon fiber-filled polyamide compound


Winona, Minnesota-based plastics compounder PlastiComp LLC has developed a long carbon fiber-filled compound, using nylon as its matrix material, that it says reaches shielding levels almost double that of comparable compounds, while also being more cost-efficient and retaining better mechanical properties.

The long-fiber thermoplastic (LFT) compounds the company now markets provide up to 70 dB shielding in the megahertz and higher frequency ranges. Applications are anticipated in parts and enclosures in consumer electronics....
