Fluorine recovery from fluoropolymer
Did you know?
WebFEVE based fluoropolymer coatings take advantage of the carbon/fluorine bond, which is extremely difficult to break. Carbon-fluorine bonds can absorb much greater amounts of UV energy and will keep this energy from affecting the weaker bonds/linkages in the FEVE resin polymer structure. WebPolytetrafluoroethylene (PTFE) is a fluoropolymer and is commonly known by its trade name, Teflon ®. Unique properties of PTFE include nonreactivity, hydrophobicity, a low …
A fluoropolymer is a fluorocarbon-based polymer with multiple carbon–fluorine bonds. It is characterized by a high resistance to solvents, acids, and bases. The best known fluoropolymer is polytetrafluoroethylene under the brand name "Teflon," trademarked by the DuPont Company. WebPFA offers the highest temperature rating and broadest chemical resistance of any melt-processible fluoropolymer, making it ideal for extreme chemical and thermal …
