Space EMI shielding LCP
LCP Spectrum Silence™
LCP Spectrum Silence™ is a broadband EMI shielding nanocomposite built on a liquid crystal polymer matrix for space electronics, magnetometer-adjacent hardware, and sensing systems. The dCNT-enabled filler system is engineered for greater than 30 dB/mm shielding effectiveness from 30 MHz to 110 GHz while maintaining low magnetic remanence, low outgassing, atomic oxygen resistance, and atmospheric reentry demisability.
