Shielding and Absorbing Materials are materials that have either the capability to absorb a specific type of energy such as Radio-Frequency Interference (RFI) and Electromagnetic Interference (EMI), or to significantly reduce the transmission of such energy.

3M CN4490 1.5"SQ-100 is a high-performance shielding and absorbing material that is designed to reduce the transmission of RFI and EMI. It provides superior performance and protection against wide frequency ranges and a variety of industrial applications.

3M CN4490 1.5"SQ-100 is engineered for a wide range of industrial applications, such as electronic equipment cabinets, motor control boxes, and switchgear. The material is designed to meet strict requirements for shielding performance, with a tolerance of greater than 90 dB on 10 MHz. The material is also designed to effectively shield against wide frequency ranges from 20 MHz to 1 GHz.

The combination of both RFI and EMI shielding and absorption capabilities makes 3M CN4490 1.5"SQ-100 the perfect choice for many industrial shielding applications. It is UL listed, and is designed to be used in electrical and electronic equipment enclosures. It is a low-cost solution to problems posed by EMI and RFI, as well as other environmental stress.

3M CN4490 1.5"SQ-100 is the ideal solution for applications such as radio frequency shielding, medical grade X-ray shielding, automotive electronic system shielding, and industrial X-ray and ultrasonic imaging systems. The material is also suitable for highly sensitive medical and aerospace applications. The product is UL-204 rated for plating-grade metal fabrications, and is UL-20 listed for Hi-V applications. The product is designed for high temperatures up to 500°F (260°C), and meets the European (CE) and US (FCC) standards for environmental protection.

The working principle of 3M CN4490 1.5"SQ-100 is simple. The material is designed to stop EMI and RFI from penetrating the protected area. The material\'s multiple layers of fabric provide both absorption and reflection properties, thus preventing both multi-directional and single-directional transmissions. The material also dissipates the EMI and RFI energy into heat, thus preventing any further transmission.

The material has an elevated static electrical capacity rating of 500 volts, and a 500-volt electrical noise immunity rating. The high-stability design of 3M CN4490 1.5"SQ-100 also reduces the accumulation of heat in the shielded area, thus preventing device failure due to high temperatures. In addition, the material is lead- and halogen-free, making it safe for use in the most sensitive equipment.

When properly applied, 3M CN4490 1.5"SQ-100 can provide superior performance and protection against wide frequency ranges and a variety of industrial applications. This high-performance shielding and absorbing material is engineered for a wide range of industrial applications, and can effectively stop the transmission of EMI and RFI.
