High frequency elastic absorbing material

High frequency elastic absorbing material is a material specifically designed to absorb high-frequency electromagnetic waves. It combines the flexibility of elastic materials with the electromagnetic wave absorption characteristics of absorbing materials, and has a wide range of application prospects.

Definition and Characteristics

• Definition: High frequency elastic absorbing material is a special type of material. When electromagnetic waves encounter this material, the energy will be absorbed by the material without being reflected or transmitted, thereby isolating or weakening the electromagnetic waves.

• characteristic:

  • Broadband absorption: capable of achieving absorption effect over a wide frequency range, suitable for electromagnetic waves of different frequencies.
  • High absorption efficiency: capable of effectively absorbing most of the energy of incident electromagnetic waves, reducing reflection and transmission.
  • High temperature resistance: able to maintain stable absorption performance in high temperature environments, suitable for high-temperature application scenarios.
  • Flexibility: It has a certain degree of elasticity and softness, suitable for covering or coating complex shaped surfaces.
  • Durability: It can be used stably for a long time and is not easily aged or damaged.

Preparation process

The preparation process of high-frequency elastic absorbing materials mainly includes physical methods, chemical methods, and composite methods.

• Physical methods, such as grinding, pressing, melt spinning, etc., mainly refine, mix, and shape raw materials through physical means to prepare materials with absorbing properties.
