3M 1181 1" X 4"-100

RFI and EMI - Shielding and Absorbing Materials

3M 1181 1" X 4"-100 is an advanced shielding material that has been widely used in many industries. This type of RF and EMI shielding material is designed for a range of electrostatic noise protection applications. It is made from thick copper foil with an acrylic-based pressure-sensitive adhesive backing. The shielding material is designed to absorb and reduce both radio frequency interference (RFI) and electromagnetic interference (EMI).

Application Field

The 3M 1181 1" X 4"-100 shielding material is a cost-effective solution for applications ranging from automotive electronics and aircraft control systems to medical imaging equipment and wireless networks. It is suitable for use in both high- and low-temperature applications. The thick copper foil provides excellent protection against electromagnetic interference and electrical shock. In addition, the pressure-sensitive adhesive backing ensures good adhesion to metal or plastic surfaces.

Working Principle

The 3M 1181 1" X 4"-100 shielding material is based on the principle of electromagnetic shielding. The thick copper foil absorbs and reflects the electromagnetic radiation emitted by components, thus avoiding the interference of signals. The acrylic-based pressure-sensitive adhesive backing also helps avoid electrical shocks. Additionally, the shielding material is designed to dampen any electrical noise generated by components.

As an advanced shielding material, the 3M 1181 1" X 4"-100 is the perfect choice for applications requiring high level of RF and EMI protection. The thick copper foil absorbs and reflects the electromagnetic radiation, while the acrylic-based pressure-sensitive adhesive backing ensures good adhesion to metal or plastic surfaces. This shielding material is perfect for applications such as automotive electronics, aircraft control systems, medical imaging equipment and wireless networks.
