Carbodiimide composition for acoustically matching layer, process for producing a formed article for said layer and ultrasonic transducer using said formed article

摘要

It is an object of the present invention to provide a composition for acoustically matching layer, having a sufficient mechanical strength to allow itself to be easily formed, and capable of giving an acoustically matching layer highly stable in characteristics over extended periods even under high temperature, high humidity conditions. <??>The present invention provides a composition containing a carbodiimide resin for acoustically matching layer, where the composition may further contain inorganic hollow bodies or inorganic hollow bodies and another reactive resin; process for producing a formed article of acoustically matching layer by curing and forming under heating the composition in a mold for the acoustically matching layer; and ultrasonic transducer using the same composition and ultrasonic transducer using the same formed article.
