Abstract
Un polimero espanso cellulare è ottenuto da una miscela comprendente: cloruro di polivinile, almeno un isocianato, almeno una anidride, almeno un agente gonfiante, almeno un plastificante, ed almeno un composto stabilizzante al calore. Secondo l'invenzione, la concentrazione del plastificante nella miscela è tale che l'allungamento al taglio del polimero risulta compreso tra il 40% ed il 52%.
