Abstract

Las espumas poliméricas, biodegradables, expandidas y extruídas se obtienen utilizando polímeros biodegradables y formiato de metilo que no es VOC ambientalmente benigno como agente de soplado. El agente de soplado puede ser una combinación que incluye además por lo menos un co-agente de soplado, preferiblemente una especie que no daña al medio ambiente (por ejemplo, que no es SOC), el cual es ya sea un co-agente de soplado físico (por ejemplo un agente inorgánico, hidrocarburo, hidrocarburo halogenado, hidrocarburo con grupo (s) funcional(es) polar(es), agua o cualquier combinación de los mismos) o un co-agente de soplado químico o combinaciones de los mismos. La combinación del agente de soplado puede incluir cualquier combinación de formiato de metilo y uno o más co-agentes de soplado. La espuma polimérica puede incluir un polímero biodegradable o sus combinaciones con otros polímeros biodegradables o polímeros convencionales (que no son biodegradables). Las combinaciones del agente de soplado basadas en formiato de metilo producen espumas estables para varias aplicaciones, que incluyen recipientes, sistemas de empaque, así como también para el aislamiento y acojinamiento protector. También se proporcionan procesos para la preparación de estas espumas.
