Manufacturing process of sealing element for methyl tert-butyl ether (MTBE) production equipment including use of fluoroelastomer

摘要

(A) from 33 to 75 mol% of ethylene tetrafluoride (TFE); (b) 15 to 45 mol% of perfluorinated vinyl ether (PVE); (c) 10 to 22 mol% of vinylidene fluorine (VDF). These materials have high resistance to polar solvents and bases, excellent comprssin ser at high temperatures, low Tg and excellent processability. Thus, the fluoroelastomers are particularly suitable for the production of plant sealing elements [O-rings] for producing methyl tert-butyl ether (MTBE).
