Optimization of the polymer foam process by the residence time distribution approach / Mathieu Larochette in Industrial & engineering chemistry research, Vol. 48 N° 10 (Mai 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 10 (Mai 2009) . - pp. 4884–4891 Titre : Optimization of the polymer foam process by the residence time distribution approach Type de document : texte imprimé Auteurs : Mathieu Larochette, Auteur ; Didier Graebling, Auteur ; Djamel Nasri, Auteur Année de publication : 2009 Article en page(s) : pp. 4884–4891 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Polystyrene  foaming  Residence  time  distribution  Extrusion  process  Reactors Résumé : In this work, we used the residence time distribution to study the polystyrene foaming during an extrusion process. The extruder associated with a gear pump is simply and quantitatively described by three continuously stirred tank reactors with recycling loops and one plug-flow reactor. The blowing agent used is CO2 and is obtained by thermal decomposition of a chemical blowing agent (CBA). This approach allows the optimization of the density of the foam in accordance with the CBA kinetic of decomposition.
