摘要: A multilayer backing for an ultrasonic transducer array comprises at least two layers in contact with each other. The first layer is formed from a composition comprising epoxy resin base and powder. second base, powder, one of phenolic shell micro-balloon plasticizer. more rigid than the so that provides mechanical support array, while maximal sound absorbance.
