Pentafluoroethyl trifluorovinyl ether

Description of Pentafluoroethyl trifluorovinyl ether

Pentafluoroethyl trifluorovinyl ether (CAS: 10493-43-3), also known as perfluoro(ethyl vinyl ether), is a fluorinated vinyl ether monomer. As a key comonomer in fluoropolymer synthesis, it copolymerizes with tetrafluoroethylene to produce perfluoroelastomers, offering exceptional chemical resistance, thermal stability, and low permeability for seals, O-rings, and gaskets in harsh environments such as aerospace, oil & gas, and semiconductor industries.

Application of Pentafluoroethyl trifluorovinyl ether

Pentafluoroethyl trifluorovinyl ether (PEVE), a fluorinated vinyl ether monomer, is primarily utilized as a comonomer in the synthesis of advanced fluoropolymers, copolymerizing with tetrafluoroethylene to produce perfluoroelastomers for exceptional chemical resistance, thermal stability (up to 300°C), and low gas permeability. These materials are essential for seals, O-rings, gaskets, and hoses in demanding sectors including aerospace, oil & gas extraction, semiconductors, and chemical processing. Additionally, PEVE enables the development of specialty coatings, lubricants, surfactants, and low-surface-tension materials for hydrophobic applications. In pharmaceuticals, it supports agrochemical intermediates and drug delivery systems.

Storage of Pentafluoroethyl trifluorovinyl ether

It should be kept in a cool (2-8°C), well-ventilated area away from ignition sources, heat, sparks, and open flames. Use approved, labeled cylinders in an upright position, secured against tipping. Protect from sunlight, physical damage, and electrostatic discharge. For long-term storage, maintain under inert conditions if possible. Ensure emergency eyewash and ventilation to mitigate asphyxiation risks.
