A fluoropolymer is a fluorocarbon-based polymer with multiple carbon–fluorine bonds. It is characterized by a high resistance to solvents , acids , and bases . The best known fluoropolymer is polytetrafluoroethylene under the brand name "Teflon," trademarked by the DuPont Company.
Xylan coatings can be one-, two- (primer and top-coat), and three- (primer, mid-coat, top-coat) coat conventional and reinforced (filled) coating systems. The fluoropolymers utilized in Xylan coatings consist of PTFE, PFA, and FEP. The properties listed below may not apply to all Xylan coatings as the fluoropolymer and resin content and type ...
Polyvinyl fluoride is a thermoplastic fluoropolymer with a repeating vinyl fluoride unit, ... PVF is usually converted into thin films and coatings. However, ...
Gore-Tex is a brand of expanded PTFE (ePTFE), a material incorporating a fluoropolymer membrane with micropores. The roof of the Hubert H. Humphrey Metrodome in Minneapolis, US, was one of the largest applications of PTFE coatings. 20 acres (81,000 m 2) of the material was used in the creation of the white double-layered PTFE-coated fiberglass ...
Polyvinylidene fluoride or polyvinylidene difluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Its chemical formula is (C 2 H 2 F 2) n. PVDF is a specialty plastic used in applications requiring the highest purity, as well as resistance to solvents, acids and hydrocarbons.
The September 11 attacks and resulting fires caused the release of toxic chemicals used in materials such as stain-resistant coatings. [220] First responders to this incident were exposed to PFOA, PFNA, and PFHxS through inhalation of dust and smoke released during and after the collapse of the World Trade Center.
Durable water repellent, or DWR, is a coating added to fabrics at the factory to make them water-resistant (hydrophobic). Most factory-applied treatments are fluoropolymer based; these applications are quite thin and not always effective.
A superhydrophobic coating is a thin surface layer that repels water. It is made from superhydrophobic ... Fluorinated silanes [10] and fluoropolymer coatings.
