CHO-SEAL® 1270 is an ultra-soft moulded elastomer EMI shielding gasket.
It is ideal for use in designs where superior mechanical performance, excellent electrical conductivity, and long term stability are required.
Typical applications are 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 ShoreA hardness of 35 (+/-5) and a low compression set figure of just 9%.
Shielding effectiveness is greater than 70dB between 100 MHz and 10 GHz.
The material is available in various product forms including compression moulded sheets, die-cut parts and custom moulded shapes.
