How to apply flexible dielectric absorbing composite materials in national defense and military industry

Time:2021-05-25Number:1462

Research PlatinumFlexible dielectric absorbing composite materialIt is a composite material series composed of an elastic silicone rubber dielectric layer and an absorbing layer. This series of products provides both isolation and absorption of RF and microwave signals. The dielectric layer is located between the absorbing material and the circuit toAbsorberMinimize the impact on circuit signals while providing additional insulation protection.

This series of products can be cut into complex shapes using die-cutting or waterjet cutting, and can also be backed with adhesive to adhere to different surfaces.
