Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, which is widely used and can be used as a PTFE sheet. One of the most well-known and recognized brands on the market is DuPont's Teflon.
PTFE is a fluorocarbon solid because it is a high molecular weight compound consisting of carbon and fluorine. PTFE is hydrophobic: neither water nor water contains wet PTFE, because the fluorocarbons exhibit a reduction in the high electronegatability of fluorine
PTFE is a fluorocarbon solid because it is a high molecular weight compound consisting of carbon and fluorine. Polytetrafluoroethylene has one of the lowest coefficient of friction for any solid known to humans, and this unique feature is suitable for applications that require low levels of resistance. PTFE is hydrophobic, which does not mean that the water does not contain water wet PTFE, because the fluorocarbons exhibit a London dispersibility due to the high electronegativity of fluorine.
PTFE is a thermoplastic polymer, which is a white solid at room temperature and a density of about 2200 kg / m3. It has a melting point of 600K. It maintains high strength, toughness and self-lubricating properties at low temperatures as low as 5K and at temperatures above 194K polytetrafluoroethylene from the overall effect of carbon fluoride to obtain its performance, as with all fluorocarbons. It is known that the only chemical substances that affect these carbon-fluorine bonds are highly reactive metals such as alkali metals and, at higher temperatures, metals such as aluminum and magnesium, as well as fluorinating agents such as xenon xylene and cobalt.
PTFE is used as a non-stick coating for pots, cookers and even industrial food processing machines. It is very non-reactive and partly because of the strength of the fluorocarbon bonds and is therefore commonly used in the selection of materials for corrosive and reactive chemicals in containers and pipelines. When used as a lubricant, PTFE can reduce mechanical friction, wear and energy consumption.
