Kynar Polyvinylidene Fluoride

KYNAR polyvinylidene fluoride, the homopolymer of 1, l-difluo-roethene, is a tough, engineering thermoplastic that offers a unique balance of properties. It has the characteristic stability of fluoropolymers when exposed to harsh thermal, chemical, and ultraviolet environments, while the alternating CH 2 and CF 2 groups along the polymer chain provide a unique polarity that influence its solubility and electric properties. Thus, KYNAR resins, in addition to being readily melt-processed by standard methods of molding and extrusion, especially at elevated temperatures, can be dissolved in polar solvents such as organic esters and amines.
