For over 40 years, DuPont™ has been relentless in pursuing improvement in the manufacture of perfluoroelastomer (FFKM) parts. Elastomeric parts typically consist of three components: a polymer chain (the backbone of the elastomer), a crosslinking system (which links the polymer chains together and is the key to elasticity and sealing performance), and a filler system (used to enhance mechanical properties). Based on extensive experience, DuPont™ adjusts these components to optimize seal performance.
