UN METODO PARA FABRICAR UN MATERIAL POLIMERO,PERFILADO,PARA AMORTIGUAR VIBRACIONES Y AISLAR EL SONIDO

摘要

Disclosed is a self-adhesive sheet of vibration damping and sound insulating material composed of a vinyl acetate homopolymer material together with a filler, a plasticiser, and a mineral filler in an amount up to 80% by weight wherein the composition comprises not more than 20% micaceous material by weight. The sheet is produced by a continuous process wherein mixing occurs at 170 DEG C. to 190 DEG C. and the continuous sheet is formed at 60 DEG C. to 120 DEG C.
