In the field of EMI shielding, gaskets are often hard and rigid, requiring high compression forces to achieve effective sealing. Parker Chomerics addresses this with the CHO-SEAL 1299: a conductive elastomer gasket with low hardness (45 Shore A) that still provides excellent shielding and corrosion resistance.
The innovation lies in the composition: passivated, silver-plated aluminum particles in a fluorosilicone binder. This makes the gasket not only effective against electromagnetic interference but also resistant to aggressive chemicals and corrosion on aluminum. Thanks to its low durometer, the CHO-SEAL 1299 can be used in sensitive interfaces where traditional gaskets require excessive force during assembly, potentially damaging enclosures or components.
The CHO-SEAL 1299 is available in pre-formed molded shapes such as O-rings and customer-specific designs, as well as sheet material suitable for precision die-cutting or cutting with a knife or water jet. An optional electrically conductive PSA adhesive layer is also available, enabling simple and reliable installation.
This unique combination of softness, shielding, and durability makes the CHO-SEAL 1299 ideal for portable electronics, military communication modules, UAVs such as drones, robotics, and marine electronics. Wherever compactness, reliability, and corrosion resistance are required, this product provides a dependable and distinctive solution.
