Abstract

Se proporcionan métodos para formar películas de espuma polimérica sin talco y películas poliméricas sin talco. Por ejemplo, un método para formar una película de espuma polimérica sin talco puede incluir transportar una mezcla que incluye i) un material polimérico, ii) un agente de soplado físico supercrítico, y iii) un agente de soplado químico a una extrusora que incluye una matriz, calentar la mezcla hasta una temperatura superior a una temperatura de descomposición del agente de soplado químico, extruir la mezcla calentada a través de la matriz para formar un precursor de película de espuma polimérica, y procesar el precursor de película de espuma polimérica para formar la película de espuma polimérica sin talco que tiene una porosidad mejorada en un rango de 20 por ciento a 45 por ciento.Methods for forming talc-free polymeric foam films and talc-free polymeric films are provided. For example, a method of forming a talc-free polymeric foam film may include conveying a mixture including i) a polymeric material, ii) a supercritical physical blowing agent, and iii) a chemical blowing agent to an extruder that includes a die, heating the mixture to a temperature above a decomposition temperature of the chemical blowing agent, extruding the heated mixture through the die to form a polymeric foam film precursor, and processing the polymeric foam film precursor to form the talc-free polymeric foam film having improved porosity in a range of 20 percent to 45 percent.
