Perfluorocarbon plastic

Experimental Design Test chamber type and size Materials that can be dissolved by water or loosened by pecking should not be used. Stainless steel, galvanized steel, or materials coated with perfluorocarbon plastics are acceptable. Any design is acceptable provided the birds are able to move about freely and pens kept clean. 

These often are called perfluoro- compounds, which indicates that all available hydrogens of the parent compound are replaced by fluorine. Thus per-fluorocyclohexane is (CF2)e- A widely used perfluorocarbon is the plastic material -FCF2-)t7, which is produced in quantity by radical polymerization of tetrafiuoroethene ...

Vertrel KCD-9547 is a proprietary azeotrope-like blend of Vertrel XF hydrofluorocarbon with trans-1,2-dichioro-ethylene and cyclopentane. It is ideally suited for use in vapor degreasing equipment to remove light oils, fingerprints, and particulate contaminants. Vertrel KCD-9547 is specially formulated to provide a high degree of compatibility with plastics, elastomers, and other nonferrous metals, such eis in aerospace parts. Vertrel KCD-9547 is nonflammable, has "zero" ozone depletion potential, and heis low global warming potential. It can replace CFC-113,1,1,1 -trichloroethane (1,1,1 -TCA), hydrochlorofluorocarbons (HCFC), and perfluorocarbons (RFC) in many applications. 

For many years a legend has been perpetrated that polytetrafluoroethylene (FIFE) and its perfluorinated copolymers are insoluble. Yet, a patent was issued as early as 1950 covering the plasticization of PTFE. In the mid-1980s. Smith and Gardner reviewed the subject of PTFE-perfluorocarbon solution thermodynamics and... 

Many non-chlorinated hydrocarbon- or petroleum-based materials are used as solvents. High molecular weight esters used in cleaners include alkyl acetates and dibasic acid esters. Many of the alternative solvents are not compatible with plastics. An exception is the perfluorocarbons, which, unfortunately, are poor solvents. The perfluorocarbons can be blended to give...
