ESPCI, together with IMP (Lyon) and CEMEF (Sophia-Antipolis) are organizing a First workshop on Flow and Processing of Highly Filled Polymers


Flow and Processing of Highly Filled Materials

Location :Institut Pierre-Gilles de Gennes -PARIS January 28-29, 2016
supported by : the Groupe Français de Rhéologie , the HUTCHINSON-IMP joint lab, the TOTAL-ESPCI chair, the Saint GOBAIN-X-ESPCI chair, the MICHELIN-ESPCI chair
Organizing committee :
François Lequeux
Philippe Cassagnau
Rudy Valette
Guylaine Ducouret

Framework and objectives

This workshop aims to explore the recent advances in Highly Filled Materials a relevant topic widely encountered in the field of rubber, thermoplastics, concrete suspension and ceramic pastes. The current tendency is to strongly increase the filler concentration, but this results in many new processing issues. Indeed these systems no longer behave like classical polymer melts, but more similar to pastes and slurries, the rheology of which remains puzzling. On the academic side, much progress is emerging in the field of flow and processing of these highly concentrated systems, and various experimental tools and models have been developed.
This workshop focused on in-depth discussion, is open to engineers and researchers from academia and industry.
Registration fee covers lunches each day and dinner : 140€
Registration will open October 15, 2015
Registration dead-line : January 10, 2016


January 28 (12:00am) – January 29 (2:00pm)
