Abstract

Mejoras introducidas en la producción de hojas de plásticomicroporosa muy permeablespartiendo de una resina sintética en polvoun plastificante para la resinaun material en polvo formador de porossoluble en aguay un disolvente volátil para el plastificantede poca o ninguna acción disolvente de la resina; siendo estos componentes íntimamente mezclados en frío hasta formar una crema de suave consistencia de elaboración; siendoluego la crema extendida sobre un portador y el disolvente volátil eliminado por evaporación a una temperatura relativamente baja (por ejemplo90º C); después de lo cual la lámina o plancha se calienta a una temperatura elevada ( por ejemplo170ºC) hasta hacer que la resina y el plastificante forman un gelse enfría luegose elimina por lixiviación el material formador de poros y se seca la plancha o lámina.
