Rubber patch type absorbing material is a composite material that combines rubber substrate with absorbing agents (such as iron-based materials, conductive particles, etc.), and has excellent electromagnetic wave absorption performance.
Material composition and characteristics
1. Composition materials
- Rubber substrate: Rubber substrate endows the material with good flexibility and mechanical strength, enabling it to adapt to various complex shapes and installation environments. Common rubber substrates include silicone rubber, chloroprene rubber, etc.
- Absorbent: Absorbent is a key component for materials to achieve electromagnetic wave absorption, usually including ferrite powder, carbonyl iron powder, conductive particles, etc. These absorbers can effectively convert electromagnetic wave energy into thermal energy or other forms of energy, thereby reducing the reflection and transmission of electromagnetic waves.
2. Main characteristics
- Efficient absorption: Rubber patch type absorbing materials have efficient electromagnetic wave absorption capabilities in specific frequency bands, which can effectively reduce electromagnetic radiation and interference.
- Thin and flexible: The material has a thin thickness and good flexibility, making it easy to install and use on various devices.
- Strong durability: It has good weather resistance and corrosion resistance, and can maintain stable performance for a long time in harsh environments.
- Controllable process: By selecting different substrates and absorbers, as well as adjusting the formulation and process parameters of materials, the optimization and control of material properties can be achieved.
