Chomerics Europe has introduced an ultra-soft moulded elastomer EMI shielding gasket. CHO-SEAL 1270 is dedicated for use in designs where superior mechanical performance, excellent electrical conductivity, and long term stability are required. Typical applications can be found in handheld electronics, infotainment systems, test equipment, military electronics, navigation devices, ruggedised computers and routers CHO-SEAL 1270 consists of silver plated copper particles dispersed within a silicone elastomer.
The material has a typical Shore A durometer hardness of 35 +/- 5 and a compression set figure of 9%. Shielding effectiveness is greater than 70dB between 100 MHz and 10 GHz. The new material is available in various product forms including compression moulded sheets, die-cut parts and custom moulded shapes. Available thicknesses range from 0.25mm (0.010in.) to 3.18 mm (0.125 in.).
