Abstract

Методът включва реакция на полиизоцианат и два различни полиола при подходящи условия за разпенване. Полученият твърд пенополиуретан се подлага на смачкване до превръщането му в мека пяна, която се подлага на топлинна обработка. Получените меки пениимат температура на встъкляване между -100 и +250С.
