Silver-Plated Aluminum in a Silicone Binder
CHO-SEAL 1285 is a top-tier product renowned for its exceptional performance in challenging operating environments. Crafted with Silicone Elastomer and Silver-Aluminium filler material, it offers unmatched durability and reliability. Its technical specifications guarantee suitability for portable, exposed conditions with exposure to Electromagnetic Pulses (EMPs). Notably, it excels in noise shielding, providing a level of 100 to 109 dB, crucial for noise-sensitive applications. Meeting MIL-DTL-83528 Type B standards ensures compliance with stringent industry requirements. With a durometer of 65 (Shore A) and a tensile strength of 200 psi, it promises robustness under pressure. The Pressure Sensitive Adhesive (PSA) backing simplifies installation, while its maximum operating temperature of 160°C broadens its applicability. CHO-SEAL 1285’s thermal conductivity of 2.2 ensures efficient heat dissipation. Additionally, it offers a lengthy shelf life of 12 months with PSA and indefinitely without. With a material thickness of 0.02 inches and generous dimensions of 15 inches width by 10 inches length, it provides versatility and ease of use, making it an indispensable choice for applications requiring superior shielding and reliability.
CHO-SEAL 1285 is a silver-plated aluminum filled elastomer EMI shielding gasket in a silicone 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.
