Case Study Icon FAFor over 40 years, DuPont™ has been relentless in pursuing improvement in the manufacture of perfluoroelastomer 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.

Case Study Icon FABenefits of using Kalrez® O-rings:
Reduce Maintenance Costs:
  DuPont™ Kalrez® parts help stretch your mean time between repair (MTBR) and lower your maintenance costs
Increase Productivity:  By reducing the frequency of seal changes, repairs, and inspections
Increase Safety:  Lasting longer and performing better than other elastomers, Kalrez® helps reduce the risk of chemical exposure from seal failure
Reduce Fugitive Emissions:  Kalrez® can help you reduce leaks and fugitive emissions for improved compliance with environmental regulations
Maintain Process Purity:  Resist degradation in harsh chemicals, maintain seal force at high temperatures, contain few ingredients that extract into the process, provide lower outgassing in vacuum sealing, and meet stringent FDA regulations for purity and cleanliness
ISO 9001 Quality Assured with Full Traceability: Made only by DuPont™, Kalrez® parts are manufactured in ISO 9001 quality certified facilities and packaged in bar-coded  bags
