THERMOSETTING POLYAMIDE FOAM AND USE THEREOF, AND METHOD FOR PRODUCING THERMOSETTING POLYAMIDE

摘要

A thermosetting polyamide foam which is produced by reacting a polyisocyanate compound and a polyester carboxylic acid under a condition, wherein an NCO index is 1.6 or more, using a compound having a P=N bond as a catalyst. The polyamide foam is excellent in heat resistance (thermal decomposition characteristics) and mold formability, and thus, can be suitably used as a heat-resistant damping material, a heat-resistant sound-absorbing material and a heat-resistant cushioning material.
