Abstract
Przedmiotem zgłoszenia jest sposób wytworzenia kompozycji elastycznej pianki poliuretanowej z zastosowaniem regulatora komórek i foli ochronnej, który charakteryzuje się tym, że w kompozycji poza co najmniej dwoma poliolami znajduje się regulator komórek w postaci substancji woskowej, silikonowa substancja powierzchniowo czynna, a podczas spieniania mieszaniny reakcyjnej kompozycji jej powierzchnia pokryta jest folią polietylenową.The subject of the application is a method of producing a flexible polyurethane foam composition using a cell regulator and a protective film, which is characterized in that in addition to at least two polyols there is a cell regulator in the form of a waxy substance, a silicone surfactant, and during foaming the reaction mixture of the composition its surface is covered with a polyethylene film.
