Overcoming Barriers in PEEK Molecular Weight Testing.
Polyether ether ketone (PEEK) is a standout material in the world of high-performance polymers, prized for its strength, thermal stability, and chemical resistance. However, these same properties that make PEEK so valuable also make it notoriously difficult to analyze – especially when it comes to determining molecular weight using size-exclusion chromatography (SEC), also known as gel permeation chromatography (GPC).
At SGS PSI, we’re leveraging a powerful chemical strategy to overcome this challenge: derivatization with 1,2-ethanedithiol. This…
