Preparation process and composition used therein, based on thermoplastic polymers for water-proofing and sound-proofing applications

摘要

Process for mixing and subsequent lamination by calendering of water-proofing and/or sound-proofing compositions by using a system of antiskid rollers. The thermoplastic compositions object of the disclosed process are comprised essentially of ethylene/ alpha -olefin copolymers with a proportion of plastifier higher than 13 %. The thermoplastic compositions thus obtained may be part of stratified laminated materials both in the water-proofing field and the sound-proofing field, in any of the applications.
