Parker Chomerics SOFT-SHIELD 3800 is an electrically conductive fabric over a silicone foam EMI shielding and electrical grounding gasket meant for low-closure force and high temperature electronics applications. SOFT-SHIELD 3800 profiles come in complex and unique non-rectangular shapes and are an extension of the rectangular profiles of Parker Chomerics SOFT-SHIELD 3700 product of EMI and grounding gaskets. Both SOFT-SHIELD 3700 and SOFT-SHIELD 3800 are low cost solutions to EMI shielding for electronics applications across a number of industries.

SOFT-SHIELD 3800 is comprised of an electrically conductive nickel-plated copper polyester taffeta weave fabric wrapped around open cell silicone foam. This wrap around technology grounds the gasket from point to point, creating an electrically conductive solution to eliminate EMI gaps. With an operating temperature range up to 125°C, SOFT-SHIELD 3700 and 3800 are ideal for applications exposed to high temperatures where a UL 94 V-0 requirement exists.

SOFT-SHIELD products typically require less than 1 lb./inch (0.175 lb/mm) of closure force for effective electrical contact. This product takes less than <10% compression set, resulting in reliable and repeatable shielding performance over the life of a device. SOFT-SHIELD 3800 is an excellent shielding and grounding alternative to traditional spring finger type products.
