헥사플루오르프로필렌-비닐리덴 플루오리드 공중합체 화학적 특성, 용도, 생산

• 화학적 성질

  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.

• 용도

  Wire and cable coatings, flexible and corrosion-resistant tubing, and liners for pipes and tanks.

• 생산 방법

  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.
