Description of 2-(Perfluoropropoxy)Perfluoropropyl Trifluorovinyl Ether
2-(Perfluoropropoxy)perfluoropropyl Trifluorovinyl Ether (CAS: 1644-11-7), also known as Perfluoro(5-methyl-3,6-dioxanon-1-ene) or PPVE-2, is a highly fluorinated vinyl ether monomer. This compound is widely used as a comonomer in the copolymerization of specialty fluoropolymers, imparting excellent chemical resistance, thermal stability, low surface energy, and superior weatherability.
Application of 2-(Perfluoropropoxy)Perfluoropropyl Trifluorovinyl Ether
High-Performance Fluoropolymer Comonomer. Used as a key perfluoroalkyl vinyl ether (PAVE) comonomer in the production of melt-processable perfluorinated copolymers (e.g., PFA and FEP), enhancing processability, chemical resistance, and thermal stability.
Chemical Processing and Semiconductor Equipment. Imparts superior corrosion resistance and low extractables to fluoropolymers used in pipes, valves, linings, and components for harsh chemical environments and ultra-pure semiconductor manufacturing.
Aerospace and Automotive Coatings. Incorporated into high-performance coatings and seals that withstand extreme temperatures, fuels, and aggressive chemicals in aerospace and automotive applications.
Specialty Membranes and Films. Employed in the fabrication of fluoropolymer films and membranes requiring excellent weatherability, low surface energy, and long-term durability.
Storage of 2-(Perfluoropropoxy)Perfluoropropyl Trifluorovinyl Ether
It should be kept in a tightly sealed container in a cool, dry, well-ventilated area, preferably at 0–10°C in a refrigerator. Protect from air, moisture, and heat to prevent degradation or polymerization. Keep away from strong oxidizing agents, bases, and incompatible materials. Avoid exposure to direct sunlight. Handle under inert atmosphere (nitrogen or argon) if possible.
