By Liz White, UT staffAmesbury, Massachusetts-ARC Technologies Inc. of Amesbury has appointed Braintree, UK-based Kemtron Ltd as its distributor of ARC magnetic and lossy foam absorbers in the UK.ARC makes electromagnetic absorbers use iron-filled flexible elastomers including polyurethane, and says this combines iron's "highly effective energy absorption" with the good physical performance of the elastomer. To make the electromagnetic interference (EMI) absorbers, ARC uses finely milled iron powders and other specialised fillers, "blended in exacting ratios" with substrates including urethane, silicone, nitrile or neoprene rubber. The result is flexible EMI absorption sheets from 0.25 to 6.4mm thick. One ARC product is "lossy foam," made using polyurethane. This range of low-density, high-loss flexible EMI absorbers, handles "a wide range of interference control problems easily, quickly and cost-effectively," said ARC. The company combines refined carbon powders with binding agents, and the absorbent mixture is then precisely integrated into an open cell, reticulated polyurethane foam.ARC Technologies describes itself as a leading manufacturer of solutions for interference control for commercial and defence markets. ARC calls Kemtron "a leading manufacturer and supplier of gaskets and components for EMC (electromagnetic compatibility) shielding," and said the Braintreee, UK-based firm offers "a one stop shop for all EMC and sealing requirements."
