High Wycombe, Bucks, UK, 15th November 2023 – The Chomerics Division of Parker Hannifin the global leader in motion and control technologies, is introducing CHO-SEAL 6750, the lowest durometer fluorosilicone-based material in its conductive elastomer product family. This softer material enables exceptional environmental sealing and shielding with relatively low compression force. It can also be used against many materials without the risk of the plastic deforming, providing customers greater design freedom.
CHO-SEAL 6750 is a cost-effective, nickel-graphite filled fluorosilicone EMI shielding material offering high temperature capability (up to 200°C continuous use) and impressive chemical resistance. The mechanical and physical properties of the fluorosilicone (FVMQ) binder allow it to withstand harsh fluids and chemicals that include machining coolants, hydraulic fluids, mineral oils and various fuels.
As an electrically conductive fluorosilicone elastomer, the new material provides consistent EMI shielding across a broad frequency spectrum. Using the CHO-TP08 test method from Parker Chomerics, CHO-SEAL 6750 delivers good EMI shielding across a broad frequency spectrum: 55 dB at 200 kHz (H field); 129 dB at 100 MHz (E field); 100 dB at 500 MHz (E field); 115 dB at 2 GHz (plane wave); and 117 dB at 10 GHz (plane wave).
With a low Shore A durometer of 53 ± 5, CHO-SEAL 6750 is ideal for EMI shielding applications such as military electronics housings, aerospace modules, connector interfaces, telecommunications equipment and industrial products. The material offers significant value for any electronic device application that requires design flexibility without sacrificing EMI protection and environmental sealing. The new RoHS-compliant material ensures the safeguarding of sensitive electronics against the ingress of dust, moisture and more.
CHO-SEAL 6750 is available in a variety of moulded, sheet stock and die-cut/waterjet cut (non-abrasive waterjet) formats. Moulded formats include O-rings, D-rings and custom shapes. If required, sheet stock can be supplied with an electrically conductive acrylic pressure-sensitive adhesive (PSA) to aid the assembly process.
