Fluoroelastomer developed for use with steam.

A fluoroelastomer sealing compound, specifically formulated to withstand the heat and corrosive effects of high temperature steam applications, has been developed by the company. A principal component of the compound, ZF9889, is DuPont Dow Elastomers' Viton GF terpolymer, an elastomer said to provide extraordinary performance characteristics in harsh service environments. Viton products are said to be capable of withstanding temperature extremes of -40 to +400[degrees]F and are resistant to attack by the most aggressive chemicals and corrosive liquids, including concentrated nitric, sulfuric and hydrochloric acids, to name a few.

By combining Viton with several other ingredients, the company's chemists developed a compound with properties that are said to be uniquely suited for high temperature steam applications, such as steam trap seals, steam valve seals, and static and dynamic sealing components.

ZF9889 not only resists heat, it withstands the corrosive and swelling effects of solvents, as well as system cleansing agents, such as amines, which are typically used in steam applications, according to the company. When exposed to high steam temperatures, ZF9889 is said to have proved durable, with minimal swelling and compression set.
