Science of Sorona® Polymer

The only high performance fiber made with renewable resources.

DuPont™ Sorona® polymer provides a unique combination of benefits to a wide variety of applicatons.  This advanced, value-added polymer represents a major new mix-enrichment offering, with the potential for growing into a significant market over the next ten to twenty years.

A unique molecular structure

DuPont™ Sorona® polymer is a unique polymer based on 1,3 propanediol (PDO).  Its beneficial properties are derived from a unique, semi-crystalline molecular structure featuring a pronounced "kink", as shown in this image.

Sorona® polymer is a fiber-grade, which means it has a uniform micro-structure and a high molecular weight that enhances processing. It can be spun into fiber or made into fabric in many existing facilities that now process PET.  Because Sorona® polymer is manufactured in a continuous process, the variation of polymer properties is limited.  As a result, processing problems and waste generation are minimized, leading to increased productivity.
