AP-159 – Two-Stage Depressurization in Gas Dissolution Foaming: The Production of Nanocellular Materials Free of Defects

Judith Martín-de León,* Victoria Bernardo, and Miguel Ángel Rodríguez-Pérez ABSTRACT: Nanocellular polymethylmethacrylate (PMMA) is produced through a newly proposed method, a two-stage depressurization in the gas dissolution foaming process. This method modifies the depressurization step and allows controlling the pressure … Continue reading →
