Overview
The CPS series is an absorbing material for electromagnetic compatibility anechoic chambers (EMC chambers), based on low dielectric constant expandable polystyrene foam. They are composite absorbing materials, composed of electromagnetic wave absorbers and environmentally friendly flame retardants. Generally, the CPS series of absorbing materials are used in combination with ferrite tiles, thus demonstrating highly efficient electromagnetic wave absorption performance within the frequency range of 30MHz to 40GHz. In addition, the CPS series of absorbing materials have excellent flame-retardant properties.
