Short Course: Material Science Fundamentals of Absorbent Cores
The primary functional component of absorbent hygiene products is the core, which captures and retains fluid rapidly in a compact space. The two key materials in the most commonly used absorbent cores are Fluff Pulp and Superabsorbent Polymer. This short course features two subject matter experts to provide a fundamental overview of these two key components: where they come from, how they function, variables to performance, and more.

The Fallacies in Our Testing
In the late 80’s, an emerging industry depended on simple tests befitting new technology and product design. Simple tests determined the most basic properties of superabsorbent polymers, newly introduced to the absorbent hygiene industry. Simple tests determined what consumer disposable hygiene products contained SAP with rudimentary ways of comparing one product to another. Fast forward to 2020 and the products are much more complex, both for raw materials and finished products. Core construction has gone from 5% of a basic superabsorbent polymer to current designs that may contain as much as 98% of an advanced polymer. Nonwovens are no longer simple polypropylene sheets to be soft against the skin but are advanced, functional materials that take on the role of fluid addition and distribution. Yet, we are still using the simple tests that were introduced over 30 years ago while trying to establish new technologies. This presentation will discuss the fallacies in our testing and will propose some new testing concepts that are better matched to developing and evaluating the technology of a new century.

BIOGRAPHYWith a wealth of expertise in absorbent hygiene, Jim Robinson has more than 35 years’ experience in the chemical industry. For 10 years, his work with BASF focused on pulp and paper chemistry, and 25 of his years there were spent on superabsorbent polymers (SAP). Prior to joining BASF, he served as a technical service representative for Hoechst Celanese.
Mr. Robinson has been a contributor on several patents on superabsorbent polymers with hygiene and industrial applications. Now retired, his last position was Manager of Technical Service for BASF’s Hygiene Business.
Jim earned a BS in Chemistry (ACS) from Hampden-Sydney College, and an MS in Inorganic Chemistry and Spectroscopy from Duke University.
