Studies of Aflas Fluoroelastomers.

摘要

This report includes studies of Aflas, a family of Japanese fluoro elastomers, and comparison of this material with two important fluoroelastomers manufactured in the United States. While Fluorel and Viton are prepared from only fluorinated monomers, Aflas is an alternating copolymer of tetrafluoroethylene and propylene. Because of the alternating character of the polymer, Aflas possesses many of the desireable properties of Fluorel and Viton and also has some unique properties which might make it useful in applications where the other two are inferior. Differences noted in this work include dielectric constants in the range of 10 to 11 for Fluorel and viton and 2.6 for Aflas. Keywords: Elastomers, Fluoroelastomers, Viton, Fluorel, Compounding, Chemical resistance, Thermal analysis, Mechanical analysis. (jes)
