RFI and EMI shielding and absorbing materials are essential components of electrical engineering. Used in communications, broadcast, aerospace, military, transportation and healthcare, these materials help protect the user and the equipment from the adverse effects of uncontrolled and unknown radio-frequency interference (RFI) and electromagnetic interference (EMI). 1181-3/8"X18YD is one type of RFI and EMI shielding and absorbing materials that has been used for decades in a variety of installations.

1181-3/8"X18YD is a tin-plated copper material that is marketed in the form of a tape. It is available in two grades – one with a soft adhesive for general purpose and one with a high temperature adhesive for heavy duty applications. The material also features a dimpled embossed backing which provides a convenient lacing option to secure the sheet to a grounding system. The material is suitable for a wide range of temperatures, ranging from -301⁰F to +405⁰F.

The unique properties of 1181-3/8"X18YD make it an excellent choice of material for applications requiring RF and EMI shielding and absorption. The tin-plated copper provides excellent RF shielding performance while the dimpled embossed backing significantly increases the material’s overall toughness and abrasion resistance. The adhesive provides a good bond on even the roughest surfaces and ensures the shield is securely attached to the equipment.

The basic working principle behind 1181-3/8"X18YD is to shield against RF and EMI radiation by absorbing it into the material. The tin-plated copper absorbs the waves and prevents them from passing through it. In addition, the dimpled embossed backing acts as a barrier, further reducing the amount of RF and EMI radiation that is able to pass through it. The high temperature adhesive ensures that the shield is securely attached to the equipment and prevents it from becoming loose over time.

1181-3/8"X18YD is a versatile material suitable for a wide range of applications including commercial, broadcast, medical, automotive and military. It is commonly used to protect sensitive electronic equipment from the damaging effects of uncontrolled and unknown RFI and EMI radiation. Some of the most common applications include:

• Computer and server rooms
• Hospitals and medical clinics.
• Aviation and aerospace industries.
• Aircraft cabins
• Marine vessels
• Automotive and transportation industries.
• Military installations
• Communication and broadcast networks

1181-3/8"X18YD is a cost-effective and reliable material for shielding against RFI and EMI radiation. It offers excellent protection from detrimental interference and is suitable for a wide range of temperatures. It’s easy to use and the adhesive provides a secure bond for even the toughest surfaces. The dimpled embossed backing also provides a convenient lacing option for attaching the material to grounding systems. The material is perfect for applications requiring RF and EMI shielding and absorption and is commonly used in commercial, broadcast, medical, automotive and military installations.
