Abstract

SE DESCUBRE UNA ESTRUCTURA TUBULAR DE DOBLE CAPA, LA CUAL ES OBTENIDA POR CO-EXTRUSION DE POLI (CLORURO DE VINILO) Y POLI ACETATO DE ETILENO DE VINILO), DONDE LA CAPA INTERIOR, CONSTITUIDA POR POLI (ACETATO DE ETILENO DE VINILO), TIENE UN ESPESOR COMPRENDIDO EN EL RANGO DE 35 A 95% DEL ESPESOR TOTAL DE LA ESTRUCTURA TUBULAR. ESTE FABRICADO HACE POSIBLE LA ACUMULACION DE SUBSTANCIAS TOXICAS, P. EJ. PLASTIFICADORES Y LUBRICANTES, LOS CUALES DEL POLI (CLORURO DE VINILO) MIGRAN A LA SANGRE, PARA SER RETENIDOS TAN LENTAMENTE COMO SEA POSIBLE, CON LA VERSATILIDAD Y USO TIPICO DEL POLI CLORURO DE VINILO, SIENDO RETENIDO SIMULTANEAMENTE.
