What are the main shielding materials for shielding boxes?

Author:admin   AddTime:2021-04-15

The absorbing materials made by the shielding box are mainly foam absorbing materials and wave glue. Generally, small-sized shielding boxes use almost all foam absorbing materials, unless some special needs shielding boxes use wave glue or foam absorbing materials. The material of the shielding box includes Bluetooth shielding box, mobile phone shielding box and so on.

The foam absorbing material is made of high-quality polyurethane soft foam impregnated with carbon black and flame-retardant treatment, after a series of processing. Provides good electrical properties, flame retardant properties, physical properties and environmental protection properties.



Due to the small medium parameters of the foam plastic, the surface reflection is small, and the bulk absorption at the same time, there is sufficient attenuation inside, and optimized treatment, so it has good vertical incidence, oblique incidence, scattering and transmission attenuation performance.

Types of foam absorbing materials
Types of foam absorbing materials: foam solid pyramid SA type, split cone SAW type, oblique pyramid SAX type, large foam main body pyramid SAH, low frequency foam pyramid SAD type, low frequency split cone SAWD type and CAWD type, ferrite Foam pyramid SAM type, foam single-layer flat plate SAT-X, FCT type with larger transmission attenuation, foam multi-layer SML type. FRC sheet type, FRC sheet wave type.
