Abstract

Inventie se refera la un procedeu pentru realizarea unor materiale permeabile la vapori de apa, prin coagularea unui strat dintr-o compozitie de poliuretan diluata cu un lichid, cu ajutorul unui nesolvent, caracterizat prin aceea ca, în scopulobtinerii unui produs cu proprietatile pielei natruale, stratul din compozitiea de poliuretan diluat cu lichid contine cel putin 20-40% g/g compozitie de poliuretan raportat la polimer si lichid particulele de umplutura microscopica separabila si nesolvent si partivulele din materialul de umplutura, fiind astfel ales încît compozitia de poliuretan diluata cu lichid sa fie tixotropica.
