Wire Oriented in Silicone Gaskets (WOS)
|
The E/Gasket-WOS establishes EMI/RFI integrity with high attenuation Avoid the risk of EMI or environmental seal failure.
The E/Gasket-WOS, Wire Oriented in Silicone, stands up to the test. Schlegel Electronic Materials' (SEM) E/Gasket-WOS combines the benefits of two robust materials into one gasket. Its high- quality commercial or military grade silicone maintains a strong environmental seal, while a choice of wire substrates offers both high levels of attenuation and galvanic compatibility/ E/Gasket-WOS also resists compression set over a wide temperature range for lasting performance.
Available in both solid and sponge silicone, with aluminum or monel embedded wires. E/Gasket-WOS comes in sheet and strip forms-with or without silicone compatible Pressure Sensitive Adhesive (PSA).
Custom orders are available upon request. For performance characteristics and ordering information please download SEM ’s Conductive Elastomers pdf or contact your SEM representative. |
