Parker Chomerics SOFT-SHIELD® 3700 High Temperature Conductive Fabric Over Foam
Categories: Polymer

Material Notes: Description: SOFT-SHIELD® 3700 fabric over foam [fof], is a low-closure force EMI gasket rated to be used in high temperature applications (maximum temperature 125°C). This enables fabric over foam type gaskets to be used in applications where temperature requirements are grater than 70°C the products takes a major compression set. The SOFT-SHIELD® 3700 material fits a need in the automotive market place for a low cost. Low closure force, high temperature EMI/ESD gasketing. It is ideal for medical and military applications that require EMI shielding in higher temperatures. It is also ideal for IT and telecom applications that have been pushing 85°C operating temperatures.

Product Applications: Used between faceplates on blade cards, Panel seals, Cover seal, Door seals, Grounding tabs, EMI Window/vent seals and improved ground paths
