Title:

極性溶剤および塩基に対する高い耐性を有するフルオロエラストマー

Document Type and Number:

Japanese Patent JP3549570

Kind Code:

B2

Abstract:

Fluoroelastomers comprising, by mole: (a) from 33 to 75% of tetrafluoroethylene (TFE); (b) from 15 to 45% of a perfluorovinylether (PVE); (c) from 10 to 22% of vinylidene fluoride (VDF). They are endowed with high resistance to polar solvents and to bases, excellent compression set also at high temperatures, low Tg and good processability. They result particularly suitable for the manufacture of sealing elements (O-rings) for plants intended to the production of methylterbutylether (MTBE).
