Course Description

Successfully extrude plastic foams that comply with existing and new application demands (e.g., energy-efficient buildings, lightweight automotive, packaging) by employing the latest practices in the evolved art of foam extrusion.

Learn to achieve desired foam characteristics by choosing the right raw materials (e.g., foaming agents, resins), equipment, and processing conditions. Also, get tips to troubleshoot foaming issues (e.g., cell collapse, coalescence, uncontrolled foam structure).

Why should you view this course?

The penetration of plastic foams into new markets continues to increase due to their favorable characteristics: lightweight, thermal and sound insulation, shock absorption, and more. It’s time to upgrade to the evolving foam extrusion practices to stay competitive! Join this course and:

  1. Get a deeper understanding of the foam extrusion process – main parameters and how they influence the properties of the final foam product, including 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, etc.).

  3. Efficiently troubleshoot foaming issues like cell collapse, cell coalescence, cell orientation, anisotropy, and post-processing foam instability.

Who should join this course?

  • R&D people turning to foaming process to reduce weight (automotive, packaging, etc.) and looking to meet new demands in traditional applications like heat/thermal insulation, electrical insulation.

  • Developers of plastics foam needing to troubleshoot foaming issues.
