Understanding Structure-Property Relationship for Effective Polymer Selection

Experts believe that with new demands being placed on plastic parts, the performance will be even more critical. It is important to understand how such materials behave when in contact with aggressive chemicals, elevated temperature, high mechanical stresses… to avoid risking part failure!

And what is not very obvious is that the polymeric structure is important to the performance characteristics of molded parts. In fact, the variation within the properties demonstrated by different plastics arises from diversity in their structure. Before designing & producing your next plastic component, join this course to:

1. Get a deeper understanding of the relationship between molecular structure (crystallinity, polarity, creep, glass transition) and end performance.


2. Learn how structural properties of a polymer can differ as per pendant side-chain groups, branching, tacticity, molecular weight…


3. Opt for more reliable plastic by efficiently translating in-use constraints and base polymer structure into tangible selection criteria.


4. Improve performance & durability of thermoplastic parts (polyethylene, polyesters, sulfones, polyaryletherketones…) in demanding applications with practical guidance from the expert.
