Shieldite™ EPH series is a high frequency absorbing material, which is made of high permeability alloy powder and rubber by mixing, dispersing and pressing. The material can reduce electromagnetic radiation by converting electromagnetic wave emitted by electronic equipment into heat energy by means of insulation loss, magnetic loss and impedance loss.
