Course Description

Steer clear of pitfalls leading to immediate or later failure by learning how molecular weight determinations are part of failure investigation of polymeric materials​! Apparently 25% of Plastic Fail issues are related to Molecular Weight Evaluation!

Learn through real-life examples from Jeffery A. Janson who has performed over 5,000 investigations:
  • Why you should change your starting point: How instead of focusing on polymer properties first, your focus on MW evaluation will help you avoid facing failure later.
  • How to systemically evaluate MW through different techniques (GPC, GPC, MFR…)

Why should you view this course?

Time to stop overlooking Mw and ending up hiring costly expert while the solution may be obvious! Relying merely on melt flow indication listed on TDS for material selection or directly considering material properties often leads to missing important factors! Like how Mw can vary during polymerization of the material itself leading to variation in Mw distribution or, after molding leading to degradation. These can lead to immediate or later failure!

Join this course to:

  1. Go beyond technical data sheets and analyze Mw for better material selection.

  2. Understand the criticality of Mw on the molding process and performance of the plastics parts over time.

  3. Enhance your plastics part-design by understanding where MW can be altered during life cycle of the polymer.

  4. Learn techniques & principles to test Mw by choosing the right measurement method (GPC, IV, MFR…)

Who should join this course?

  • R&D formulators, Material scientists, Quality control professionals, resin manufacturers, compounders who have already faced failure issues or those who are looking to secure their production/avoid failure.

  • OEMs and molders who have incoming inspection to verify molded part specifications.

  • Markets where failure is not an option: aerospace, transport, electronics, medical.

  • This course is suitable for beginner level proficiency
