フッ化ビニリデン·ヘキサフルオロプロピレン共重 化学特性,用途語,生産方法
化学的特性
A primary advantage of fluororubber is its exceptional heat,
chemical, and solvent resistance. The copolymer is biologically
inert. The decomposition products of FPM depend
on the chemical composition of the intact polymer and also
on the conditions under which it is decomposed. The temperature
to which the polymer is subjected, the atmosphere in
which decomposition occurs, and the material of the vessel
used can alter the kinds and quantities of the decomposition
products. When a copolymer of vinylidene fluoride and
hexafluoropropylene decomposed at 550 and 800°C, carbon
monoxide and carbon dioxide were produced. Hydrogen
fluorides and other fluorocarbons have been reported as
decomposition products.
使用
Wire and cable coatings, flexible and corrosion-resistant tubing, and liners for pipes and tanks.
調製方法
Vinylidene fluoride-based elastomers have generally been
prepared by free-radical emulsion polymerization of the
monomers with organic or inorganic peroxide initiators.
Low-molecular-weight fluid or semifluid polymers have
been made with various chain transfer agents, special initiators,
or dehydrofluorination oxidation methods.
