Description:

This series of webinars explored methods of analysis for polyurethane (PU) raw materials (isocyanates and polyols), the variability that may be encountered, and this variability as it relates to specifications. They also introduced different types of applications tests and define performance parameters typically measured. Participants that are new to the polyurethane industry or to polyurethane raw material QA/QC will find the presented information beneficial, as well as those with more experience who want to know more about isocyanate and polyol analyses. Each part of the webinar series discussed the importance of measuring each of the PU raw material parameters, the equipment and methods used, the repeatability/reproducibility encountered, and potential interferences.
