POLA-H® COMPOSITE GASKETING

POLA-H ® is a composite EMI shielding and weather seal gasket strip designed for low frequency H (magnetic) field shielding, but providing outstanding E (electric) field and plain wave shielding as well.

The material consists of continuous solid copper conductive paths (ASTM-B-545) in a solid silicone pressure seal.Protruding tips of copper are plated with tin alloy (ASTM-D-152) for low contact resistance (high contact conductivity) at mating surfaces, a primary factor in achieving effective H field shielding.
