Fluoroelastomer sealer.This fluoroelastomer sealing compound has been specifically formulated to withstand the heat and corrosive effects of high temperature steam applications. The principal component of the ZF9889 compound is DuPont Dow Elastomers' Viton GF terpolymer ter·pol·y·mer n. A polymer that consists of three distinct monomers. [Latin ter, thrice; see trei- in Indo-European roots + polymer.] , an elastomer elastomer (ĭlăs`təmər), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. said to be well known for its extraordinary performance characteristics in harsh service environments. Viton products are 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, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the company. By combining Viton with several other ingredients, the company's chemists are said to have developed a compound with properties that are uniquely suited for high temperature steam applications, such as steam trap a self-acting device by means of which water that accumulates in a pipe or vessel containing steam will be discharged without permitting steam to escape. See also: Steam seals, steam valve seals, and static and dynamic sealing components. The ZF9889 product not only resists heat, it withstands the corrosive and swelling effects of solvents, as well as system cleansing agents such as amines amines (  mēnz´),n.pl organic compounds that contain nitrogen. , which are typically used in steam applications, according to the manufacturer.
