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.
