Extruding Plastic Foams to Meet Today’s Market Needs

This is a Past Course

Recorded on Apr 25, 2017

Successfully extrude plastic foams that meet challenging demands of new and existing applications (energy efficient buildings, lightweight automotive, packaging…) by employing latest practices of the evolved art of foam extrusion.

Ana Espert will show you how to achieve desired foam characteristics in practice by making the right selection of raw materials (foaming agents, resins…), adjusting formulation & processing conditions, equipment… and troubleshooting foaming issues like cell collapse, cell coalescence, uncontrolled foam structure…

Why should you view this course?

Penetration of plastic foams into new markets continues to increase due to their favorable characteristics: lightweight, thermal and sound insulation, shock absorption… It’s time to catch up with the evolving foam extrusion practices to stay in the game! Join this course and:

  1. Get a deeper understanding of the foam extrusion process – main parameters and how they influence properties of the final foam product, how to control open and closed cells...
  2. Learn how to tweak your foam extrusion process (temperature profile, die pressure, formulation conditions, raw material choice, downstream processing, equipment…)
  3. Efficiently troubleshoot foaming issues like cell collapse, cell coalescence, cell orientation, anisotropy, and post-processing foam instability.
Extrusion of Plastic Foam

Who should view this course?

  • R&D people turning to foaming process to reduce weight (automotive, packaging…) and looking meet new demands in traditional applications: heat / thermal insulation, electrical insulation
  • Developers of plastics foam needing to troubleshoot foaming issues.
