Kynar, or specifically Kynar 500, is Arkema’s trademarked brand of polyvinylidene fluoride (PVDF) resin. Though technically specific to one brand of polyvinylidene fluoride in particular, the name “Kynar” is conversationally (and inaccurately) used to describe all types of polyvinylidene fluoride resins (similar to how the word “Q-Tip” is used to describe all cotton swabs or “Kleenex” with facial tissues).
One of the world’s toughest and purest synthetic materials, PVDF is a semi-crystalline high-performance thermoplastic known as a fluoropolymer. By definition, a fluoropolymer is a plastic that has multiple carbon-fluoride bonded sections per molecule. Typically used as industrial coatings, fluoropolymers are highly resistant to chemical abrasions and damage (perhaps the best known example of a fluoropolymer is Teflon or polytetrafluoroethylene).
Similar to Teflon, Kynar is generally used as a coating material when an object, usually metal, needs to be more durable and/or resistant to chemicals or weathering. A metal roof, for instance, might be coated in a thick layer of Kynar 500 to increase durability, maintain color vibrancy and gloss, and prevent instances of corrosion and weathering. Extremely easy to clean and maintain, roofs coated in Kynar are highly resistant to sun fading, mildew, grime, and other aspects that might negatively affect the roof’s appearance.
Regarding Kynar fabrication and Kynar machining, Kynar can be precisely converted and bonded with relative ease by experienced Kynar fabricators like JC Finley. In terms of Kynar distribution and sales, the material is generally sold in cut-to-size sheets or rods of varying thicknesses and is available in several grades depending on the application(s) for which it will be used.
