 A Primer on Perfluoroelastomer (FFKM)
Perfluoroelastomer (FFKM) is a unique elastomeric polymer that plays an important role in producing sealing elements that can perform in very aggressive chemical and high temperature environments.
 A comparison of Chemraz® 505 and Kyflon™ 3060
Chemraz® 505 perfluoroelastomer o-rings were introduced in the 1990’s. They were Greene, Tweed & Co’s first perfluoroelastomer product offering. Kyflon™ 3060 has been on the market for more than eight years and its chemical structure is based on the advancements that have been made in perfluoroelastomer polymer technology.
 A comparison of Kalrez® 4079 and Kyflon™ 3000
Kalrez® 4079 perfluoroelastomer o-rings were introduced in the 1980’s. Kalrez o-rings are effective sealing elements in high-heat and aggressive chemical environments. Kyflon™ 3000 has been on the market for more than ten years and its chemical structure is based on
the advancements that have been made in perfluoroelastomer polymer technology.
