ptfe teflon gasket rod dia 15mm
Teflon is a polytetrafluoroethylene (PTFE) derived from solid fluorocarbon base material, because the molecular weight of the compound consists entirely of carbon and fluorine. The Teflon molecular structure is a long chain of carbon atoms, similar to other polymers. This long atomic chain is surrounded by fluorine atoms. The bond between carbon atoms and fluorine is very strong.
Carbon is found in all living things and is the basis of organic chemistry. This element is also unique in its ability to form chemical bonds with fellow carbon as well as many other types of elements, forming nearly 10 million known types of compounds. This element is the most stable element among other elements.
Fluorine is the most electronegative and reactive element when compared to all elements. Pale yellow, corrosive gas, which reacts with many organic and inorganic compounds, such as metal, glass, ceramics, carbon, even burning water in fluorine with a bright flame. Fluorine is very reactive so it is rarely found in a free state, fluorine is usually found to bind to other elements or compounds.
In the process of making Teflon, another chemical called Perfluorooctanoic acid (PFOA or C8) is used which is an ammonia salt. This substance is used as a surfactant in PTFE polymer emulsions. Therefore, chemicals in the nonstick coating contain various harmful metals such as mercury and PFOA substances that are carcinogens.
Teflon is also a very strong synthetic material, generally white in color. Teflon is resistant to heat up to about 250C, and above 250C Teflon starts to soften, inside the fire will melt and be difficult to become charcoal. The specific gravity is approximately 2.2 g / cmI. Teflon is not resistant to alkaline hydroxide solutions. Also less resistant to hydrocarbons containing chlorine.
