Introduction

The field of RF and EMI - shielding and absorbing materials is vast and yet often misunderstood. This article looks at the application field and working principle of the 21226190 material, which is a polymeric material that can be used for shielding and absorbing electromagnetic (EM) fields. It provides an overview of how 21226190 functions, explains the differences between shielding and absorbing, and outlines its applications in the engineering and scientific fields.

Field of Application

The 21226190 material can be used to help protect against unwanted or interfering electromagnetic radiation (EMR). It is a versatile material that can be used in a variety of applications, from aerospace to defense to industrial. It has been used in medical equipment to help reduce the impact of harmful EMR on medical staff and patients, and has been used in NASA satellites to protect them from the energetic environment of space. It is also widely used in the automotive and electronic industries to help protect against RF and EMI interference in vehicles and other RF-sensitive devices.

Working Principle

The working principle of the 21226190 material is based on shielding and absorbing EMR. Shielding involves the use of reflective surfaces to redirect the EMR away from the source or receiver, and is most often made of conductive metals, such as aluminum, copper, and silver. Absorbing involves the use of materials that are able to absorb the EMR, often through absorption of the EMR as heat energy. The 21226190 material is an absorber material, and is able to absorb a wide range of frequencies from low frequencies up to high frequency millimeter waves.

The 21226190 material is made from multiple layers of material, each optimized to absorb at different frequencies. The outer layer is made out of a conductive material, which helps to shield against EMR. The inner layers consist of a combination of foam and other absorptive materials that are designed to absorb the EMR, reducing the signal strength and preventing interference.
