Critical applications requiring high temperature stability to filter caustic gases or fluids, such as in the semiconductor, chemical processing, and petroleum/gas industries, have traditionally used polymers such as polytetrafluoroethylene (PTFE), perfluoroalkoxy copolymer (PFA), and ethylene chlorotrifluoroethylene copolymer (ECTFE).
Fluoropolymer coatings such as polytetrafluoroethylene (PTFE), polyvinyl acetate (PFA), polyvinylidene fluoride (PVDF), fluorinated ethylene propylene (FED, ethylene tetrafluoroethylene (ETFE) and ethylene chlorotrifluoroethylene (ECTFE), as well as hybrids incorporating polyphenylene sulfide (PPS) and ceramic, are in high demand.
The analyzer helped develop the ASTM Method D 7066-04, which approves the use of dimer/trimer of chlorotrifluoroethylene (S-316) for analysis of recoverable oil and grease and nonpolar material in soil by infrared determination.
Designed as an alternative for applications where high grade metals fail and PFA/PTFE are too expensive, Halar pipings and fittings offer a material composed of a copolymer of ethylene and chlorotrifluoroethylene (E-CTFE) that resists most acids, bases and solvents.
Although many fluoropolymers have been prepared, major commercial products are homopolymers and copolymers deriving from free radical polymerization of a limited number of fluoromonomers, such as tetrafluoroethylene (TFE), vinyl fluoride (VF), vinylidene fluoride (VF2), chlorotrifluoroethylene (CTFE), hexafluoropropylene (HFP), perfluoropropylvinylether (PFPVE) and perfluoromethylvinylether (PFMVE).
polyvinylfluoride, chlorotrifluoroethylene homopolymer, tetrafluoroethylene-ethylene copolyrner, vinylidenedifluoride-hexa fluoropropylene-tetrafluoroethylene terpolymer and other blends.
* ECTFE (ethylene chlorotrifluoroethylene) has a continuous-use limit of 302 F.
Most of high performance porous membranes are frequently achieved via TIPS method from a variety of polymers [6-10], such as PVDF, polypropylene (PP), polyethylene (PE), polyamide-6 (PA6), poly(phenylene sulfide) (PPS), ethylene-acrylic acid copolymer (EAA), polyethylene chlorotrifluoroethylene) (ECTFE), and poly(vinyl butyral) (PVB) etc.
For example, polymers formed by copolymerizing tetrafluoroethylene, hexafluoropropylene, chlorotrifluoroethylene, perfluoro(alkyl vinyl ether), vinylidene fluoride, or vinyl fluoride with olefin monomers can be used.
To make the dispersions, equimolar amounts of chlorotrifluoroethylene and a variety of functionalized vinyl ethers were polymerized.
