SOFT-SHIELD 3700 EMI shielding provides protection up to 125 °C

The new material is able to provide a cost effective EMI / ESD solution in a wide range of higher temperature applications in the automotive, military, medical and telecom sectors where most existing gaskets that use a urethane foam are unsuitable due to their 70°C upper temperature rating.

SOFT-SHIELD 3700 is able to achieve a shielding effectiveness of greater than 100 dB (between 50 MHz and 10 GHz) with a low closure force of just 0.175 N / mm (1lb/ in.). It is available in a choice of square and rectangular profiles to ensure optimum mechanical fit and electrical performance, the material is an ideal replacement for traditional spring finger type products in assemblies where enclosures are assembled without mechanical fixings that exert high forces, or where a wide range of tolerances exist.

Traditional urethane foam based gaskets suffer compression set when used at temperatures above 70 °C, SOFT-SHIELD 3700 meanwhile, retains its memory and exhibits excellent compression set over its -40 °C to + °125 C operating temperature range. UL 94 V-0 rating plus RoHS and REACH compliance provide designers with the reassurance of the material’s adherence to prevailing legislation requirements.
