Silver-Aluminum filled in a Fluorosilicone Binder
CHO-SEAL 1298 stands out as a premier solution tailored for demanding environments, particularly suited for applications dealing with fuels. Crafted with Fluorosilicone Elastomer and Silver-Aluminium filler material, it ensures unparalleled resilience and reliability. Its technical specifications certify its suitability for portable, exposed settings, including exposure to Electromagnetic Pulses (EMPs). Meeting MIL-DTL-83528 Type D standards underscores its adherence to stringent industry requirements. Noteworthy is its noise shielding capability, providing a level of 90 to 99 dB, crucial for noise-sensitive environments. With a durometer of 70 (Shore A) and a tensile strength of 180 psi, it guarantees durability under pressure. The Pressure Sensitive Adhesive (PSA) backing facilitates easy installation, while its maximum operating temperature of 160°C widens its application range. CHO-SEAL 1298’s thermal conductivity of 1.2 ensures effective heat dissipation. Additionally, it boasts a substantial shelf life of 12 months with PSA and indefinitely without, making it an indispensable choice for applications requiring superior shielding and reliability in challenging environments.
CHO-SEAL 1298 is a silver-aluminum filled elastomer EMI shielding gasket in a fluorosilicone binder which offers good shielding and corrosion performance. It is available in sheet form and extruded into various profiles, allowing for design and manufacturing flexibility. For use in both military and commercial applications, sheet materials can be die-cut or water jet cut to make precision parts in large quantities.
