• Description: Vinyl fluoride (VF) was first synthesized by Frederic Swarts, a Belgian chemist in 1901, by the reaction between zinc and 1,1-difluoro-2-bromoethane. Modern preparation involves the reaction of acetylene and hydrogen fluoride (HF) in the presence of a mercury- or aluminum-based catalyst. The US Environmental Protection Agency (EPA) listed VF as a highproduction- volume chemical in 1990. According to National Toxicology Program (NTP), 2005, the annual production of VF in the United States was above 1 million pounds (454 000 kg) in 1990 and approximately 3.3 million pounds (1.5 million kg) in 2001.
• Uses: Since the 1960s, VF has mainly been used in the production of polyvinyl fluoride (PVF) and other fluoropolymers. Polymers of VF have excellent resistance to degradation by sunlight, chemical attack, and water absorption and exhibit great strength, chemical inertness, and low permeability to air and water. PVF is laminated with aluminum, galvanized steel, and cellulose materials and is used as a protective surface for the exteriors of residential and commercial buildings. PVF laminated with various plastics has been used to cover walls, pipes, and electrical equipments and inside aircraft cabins. PVF is sold under the trademarks Tedlar PVF film and Dalvor. Due to increase in demand for solar panels, the demand for photovoltaic materials such as Tedlar is high, forcing the manufacturer to boost VF production. Vinyl fluoride is used primarily in the production of polyvinyl fluoride and other fluoropolymers. Polymers of vinyl fluoride are resistant to weather and exhibit great strength, chemical inertness, and low permeability to air and water. Polyvinyl fluoride is laminated with aluminum, galvanized steel, and cellulose materials and is used as a protective surface for the exteriors of residential and commercial buildings. Polyvinyl fluoride laminated with various plastics has been used to cover walls, pipes, and electrical equipment and inside aircraft cabins (IARC 1995).
