HYDROFLUORIC ACID, ANHYDROUS Resistant O-Rings and Seals
Hydrofluoric acid anhydrous (HFA), also known as hydrogen fluoride anhydrous, is a colorless, corrosive, and extremely toxic acid. It is primarily used in the production of fluorocarbons, aluminum smelting, and semiconductor manufacturing.
Common rubber failures associated with exposure to hydrofluoric acid anhydrous are discoloration, cracking, and swelling. The acidic nature of hydrofluoric acid anhydrous can cause discoloration in some rubber materials, as the acid can easily penetrate the material. Cracking can occur due to the acid breaking down the rubber’s molecular structure, causing the rubber to become brittle and prone to breakage. Swelling can also occur when the acid migrates into the rubber, causing the rubber to expand and become less resistant to stress.
FFKM Perfluoroelastomer
Markez ® high performance perfluoroelastomer O-Rings (FFKM) offer unmatched value for demanding sealing applications. Produced from nearly identical ingredients as higher priced brands, Markez ® compounds are used for high temperature o-rings and high pressure o-rings and chemical resistant o-rings that deliver similar performance to major FFKM brands, with temperature resistance up to 625oF, at a significantly lower cost. Our proprietary processing allow us to supply seals under an inch in size more efficiently.
